Electrum wallet stay on "synchronizing" last few days

[GerGys]

Hi ,

I will be very thankful if you help me!
Last few days my electrum wallet keeps on "synchronizing" and nothing change. I did some Google research and follow the tips there, but didn't help at all. I un-tick the auto-connect box, changed the servers manually... allo the electrum application in firewall... nothing. The status is still "synchronizing" with blue arrows in the right corner.
My last received transaction there is 0. I've checked it in blockchain and the status of the last transaction is "received". But in my balance is 0. I guess, because my wallet isn't connected.
Thank you in advance for your help!

You are correct that it is a connection issue and trying different servers and your firewall settings were the correct way to try to start fixing the problem.

Can you open a command prompt and see if you can ping the server you trying to connect to?

Example this is what I get right now:

This appears to be a known bug as discussed in this thread: https://bitcointalk.org/index.php?topic=2829027.0

It should be fixed in the latest 3.0.6 version of Electrum.

[GerGys]

Thanks for the replies!

TheQuin, I am not so good with that and don't know how to open that command and don't know how to do ping.
codewench, my wallet is version 2.6.4 . How to upgrade the version? Should I download the new one and delete the old one? I am worried, because I got money in my wallet.

[TheQuin]

Just download and install. It will automatically upgrade and you will not lose any settings. You should do this anyway as there is a vulnerability in versions 2.6 to 3.04. Use https://electrum.org/#download as there are many phishing sites.

[GerGys]

TheQuin , thank you!
I will upgrade the wallet now and will let you know if everything is fine.

TheQuin , thank you!

There is many fake sites who pretend to be real and legitimate Electrum site,so be careful and download only from https://electrum.org/#home . When you search for "Electrum" you may see paying add at the top of the search results,it is fake and it should be avoided at all costs.

Before upgrade be sure to have your seed safe, and that it is 100% accurate,only in case something goes wrong.

[GerGys]

Sorry for asking so much maybe stupid for you questions, but if I understand correct I should just download the last version, install it and the wallet will be updated automatic. Am I correct? And will have there the entire history and the money also, right?
Thanks in advance for your replies! I really appreciate it!

Yes.

As @Lucius just pointed out you should always have a copy of your seed phrase in case of emergency. I have upgraded many times and never needed to use it but it is a sensible precaution to take.

[GerGys]

Thank you all !
I will do that now and will let you know if everything is fine.

Hi again,
I just downloaded and installed the last electrum wallet version, but now I got two electrum icons on the desktop.
I downloaded it for here  https://electrum.org/#download - Windows Installer. Should I remove the previous wallet icon?
The problem is that my last received transaction is 0. I've checked it in blockchain and see, that is with status confirmed. But it my history and balance is 0 and don't have that amount in my balance. What should I do about it?
Thank you in advance!

Don't worry about a desktop icon. What version number is displayed at the top left of the windows? Is it now connected to the network or does it still say synchronising?

[GerGys]

3.0.6 is the version. The wallet is connected now ( I got a green in the right corner). All the history displayed correctly. Just the last transaction is with status verified, but the amount is +0. and there is no amount received. It's like I didn't receive that amount. But when I check the transaction details, it says that it's confirmed.

OK, what is the transaction id? (Right click the tx and 'details')

Then click the green circle and tell me what number Blockchain: says for blocks.

[GerGys]

Transaction ID : ae0c29d96d5e9c513222ce5950bc8071897692721271b1272812607e2139b1f3

Blockchain : 509151 blocks

Blockchain : 509151 blocks

That all looks good. The tx is confirmed although it does have 197 outputs so I don't know which one is yours or how much it is. There was a bug I think in one of the 2.8 versions that caused some transactions to be displayed with 0 value but that was fixed so I don't know what is going on here. Don't panic about it as the tx is confirmed on the blockchain the funds are safe.

I would suggest making a screenshot to show the problem and then alert the Electrum developers to the issue.

[GerGys]

Thank you very much for your help!
To be honest, I didn't expect to receive so much help here, since this is my first post here. But now I see, that here are very nice and correct people. I really appreciate your all help!
How to alert the Electrum developers about that?

To be honest that isn't something I have ever needed to do. According to the website bug reports are through Github https://github.com/spesmilo/electrum

As ThomasV is active on the forum you could try posting the screenshot I mentioned to demonstrate the problem and he might well comment.

It is a known problem which some users have recently,but the problem was to be solved with version 3.0.6.You can try to select different servers when you click on green dot-uncheck automatic selection and try to pick any other server from the list then wait to see if your transaction is show correct balance.

If this not help there is a possibility that some file in Electrum folder is corrupted,so you should try to delete blockchain_headers file in Electrum folder.It is located on  C: \Users\YourUserName\AppData\Roaming\Electrum\wallets (or %APPDATA%\Electrum\wallets) but to see appdata you need to click on File - View - Folder Option - Show Hidden Files(in Windows)

If you delete that file(only that file) your wallet will need to sync again(download that file) so give it some time for that.

Last option is clean install of Electrum(uninstall/delete all files)and then restore from seed.If you do that be sure you have 100% correct seed.

A faster way to open the hidden folder containing the blockchain_headers file is to click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the folder.

%appdata%\Electrum

This is what your search box should look like after you have copied and pasted the line above into it.



Deleting the blockchain_headers file fixed the problem for me.

[GerGys]

Thanks for your help!

"Deleting the blockchain_headers file fixed the problem for me." - if I delete this file, will this transaction appear in my wallet and balance? Because, as I said, now this transaction is verified and with amount +0.
Now my wallet is working and all other transactions are verified. Just the last one is verified and with amount +0.

Like I said earlier I was under the impression that this was an old bug that had been fixed which why is partly why I recommend upgrading rather than this, but it's worth giving it a go.

It is possible that with deleting of this file your problem could be resolved,but it is not 100% that will succeed in your case.There is a possibility that another file is corrupted also,so only solution would be to uninstall Electrum and manually delete all files in Electrum folder on the path which we mentioned earlier.

As long as you have the correct seed for your wallet there is no danger that you will lose your coins,so check your seed by clicking on symbol right next to the green dot and enter your password(if it is protected)then when you are 100% sure it's completely correct you can try to do some of the above procedures.

OP has reported this on github. Anyone who wants to follow the issue can do so here: https://github.com/spesmilo/electrum/issues/3909

Hi again, friends,

yes, I posted my question there also, because I am trying to find the best solution of my problem. The transaction's amount isn't small for me. I worked hard for it and don't want to lose it.
 I got 2 blockchain_headers file: blockchain_headers and blockchain_headers.tmp. and don't know which one I should remove from the folder.
Thank you in advance for your help!

I think you should try to solve your problem with clean install of Electrum,as I suggested in post above.It means uninstallation of Electrum program and deleting of all files in his folder.Then download latest version and restore from seed.

Regarding blockchain_headers file,I just check and have only 1 file,no tmp.,but you should delete both,it will not harm your wallet in any way.After that just start 3.0.6 version of Electrum and give it some time to sync.File is about 40 MB,so time for sync will depend of server you are connected and your internet speed.

[GerGys]

Thanks for the reply!
If I understand correct, .tmp mean, that the blockchain_headers file isn't full downloaded.
I am scared to unistall the wallet and to restore it from seed, because I just checked the seed in my saved txt and see, that I got 13 words. Is it possible to have 13 words instead 12?

At the beginning of Electrum seed contained 12 words,then from 2.0 to 2.6.4 version it have 13 words,and from next version to today it have 12 words again.But you should not to worry because Electrum seed is compatible with all versions,so your 13 words seed should work in last version of Electrum.

You can also make a backup of all files in Electrum folder before you delete them,just in case you need them.If you have some other PC you can try to install Electrum and use your seed in that way.

But before that try option with blockchian_headers file.

[GerGys]

Thanks for your reply!
I just deleted both blockchain_headers files and restart it. The synchronizing process took just a few minutes. Nothing changed. Now the wallet is connected, but the last transaction is still +0. 
Yes, I have other PC, but is on Linux. I will try now to download the 3.0.6 for Linux and to restore the same wallet, using the 13 seeds.

[GerGys]

Thank you very, very much! I really appreciate your help!
I downloaded and installed 3.0.6 on different computer (Windows) and restored my wallet, using the seeds. Now everything is fine with the transaction and the amount is in my balance.
Just have some more questions and will be happy if you help me again!
If I copy blockchain_headers file file from the working wallet and paste it to the previous wallet (which is on different computer), will make it work fine? What do you think about it?
Is it fine to have one wallet on 2 computers?

You can try if you want but now that you know you can restore from seed I'd probably prefer to delete Electrum and all the data files and do a fresh installation.

Is it fine to have one wallet on 2 computers?

Yes, no problem at all.

I'm glad that you solved the problem, probably issue was about some corrupt file which is caused by upgrade from old version of Electrum.Since you try deleting blockchain_headers file before and that did not solve problem you should not do that.Just make clean install and your wallet will work without problems.

You can have one wallet on many devices,this is not problem-only be sure that they are on clean PC,and that you set strong password.

[GerGys]

Thank you very much, friends,
I uninstalled everything from the computer (the one with not working wallet), do the installation again, restore it from the seeds and now everything is working and the last transaction is in my balance. Now have one working wallet on two computers.
Thank you very much to all, who helped me! Hope I also will be able to help to someone here!
You are all great, nice and intelligent people here!
A huge THANK YOU!
