Hello!

Already the second day I can not connect to the wallet. Hangs synchronization and does not connect.

New version electrum from 3.3.3 to 3.3.4. I tried to connect to different servers, nothing helped.

I tried to install the mobile version for android, the synchronization also can not be completed.

What can you recommend in this situation to connect to the network? Which servers to use?

Did you download from the original site? (https://electrum.org/#download)
Are you using a standard wallet with standard amount of bitcoin addresses?

I haven't used Electrum for some time (version 3.3.4) but I decided to launch it today in order to help the guy from this thread. It managed to synchronise once after relaunching Electrum a few times. Now, my wallet does not synchronise either. Don't do anything unless Electrum developers address this issue. Your coins are safe so don't worry about it. You can import your seed to some other wallet software if you have to spend your coins urgently.

I just try to open Electrum, server set to automatic and it sync in less then 10 second. No doubt it's about DDoS attack which lasts for some time on Electrum servers, therefore the only way to sync is to try on as many servers from the list.

To manually change the server click on bottom right icon (red dot), then click on Server tab -> Right click on any server -> Use as server -> Close -> Wait for sync.

In my case, the server that is currently running is : electrum.taborsky.cz

Yes, of course, the wallet was downloaded from the official site.

When trying to connect to this server, the wallet is still not synchronized

Don't have a problem last time, but when I opened my wallet today it was also stuck Synchronizing. My wallet was set to select server automatically too. I manually connected to electrum.taborsky.cz trying if it will work out like @Lucius, but it ended up Not connected. I guess I'll just wait until it gets back to normal.

oh, update: My wallet was already fully synced. What I did was:
1. Earlier I opened my wallet -> it was set to "Select Server Automatically" -> Stuck in Synchronizing...
2. Unchecked "Select Server Automatically" -> select "electrum.taborsky.cz" manually -> Ended up not Connected
3. Checked "Select Server Automatically" again and close the wallet

4. After a few minutes, I opened the wallet again
5. it's Synchronizing... for a few seconds -> showed "Server is lagging (2 blocks)" after -> then it fully synced already
6. It was automatically connected to server : electrum.hodlister.co

How much time you give to selected server in an attempt to connect and synchronize? Try to leave at least 2-3 minutes before you connect to another.

Another thing that can cause problems with sync can be corrupt blockchain_headers file which is located in Electrum folder, and by deletion of this file wallet need to download that file again ( it is only 40+ MB).

You can try to delete this file by navigate to Electrum folder :

On Windows -> copy / paste in Windows Explorer address bar -> %appdata%\Electrum
On Mac -> Open Finder - > Go to folder (shift+cmd+G) and type ~/.electrum
On Linux -> Home Folder -> Go -> Location and type ~/.electrum

This is not something that can solve the problem you and some others have, but it is worth trying.

Im having the same problem, from what ive been told on IRC wallets with a high number of transactions will struggle to synch due to the latest patch making the wallet look like ddos attack. not sure how this is going to last for Sad

Your last sentence is interesting, how do i import my coins to another wallet? I need access to my btc asap. I have coinomi and exodus wallets ready to go as well. Thanks

The only problem is that any seed generated by Electrum is not BIP44 compatible. You will have to open Electrum, select Wallet -> Private keys -> Export. Then you can sweep those private keys into Coinomi wallet. Note that a transaction will be broadcasted for each Bitcoin address. Once your transactions get confirmed, you will be able to spend your coins directly from Coinomi.

Electrum servers are being DDoS'ed. You need to manually select a server until it connects, wait until the attack is over or if you are really in a hurry, export your keys and use a different wallet.

Quote
Electrum servers are currently under a DoS attack. We are working on a more robust version of the electrum server. In the meantime, affected users should disable auto-connect, and select their server manually.

This command on the console tab (view > show console if you can't see it) will only display the private keys of addresses with unspent coins:

Code:
getprivatekeys(listaddresses(False,False,False,False,False,True))

It will be much easier to use your Master Private Key. It can be either derived from your seed or extracted from the unecrypted wallet file. Open your wallet file using notepad (it's located in %appdata% -> Electrum -> wallets) and search for xprv. Copy what's inside of inverted commas next to it and use it while importing your wallet somewhere else.

The above receive addresses are from: http ://blendergoyusuu6g.onion/blender.html <-WARNING! Probable SCAM LINK - Do not use!
I tried to contact the e-mail mailbox, but I never responded.
To the best of my knowledge... the only "official" BitBlender URL is: http://bitblendervrfkzr.onion/
Refer here: https://bitcointalk.org/index.php?topic=436467.0

Looks like you may have sent coins to a fake "blender".


Also, It might simply be a matter that your Electrum version is too old. As per the notification on Electrum website, versions older than 3.3 will not be able to connect to Electrum servers:
Warning: Electrum versions older than 3.3 can no longer connect to public servers, and must be upgraded. This is in order to prevent user exposure to phishing messages. Do not download Electrum from any another source than electrum.org.

And the notification on Tails website:
Known issues
ELECTRUM IS OUTDATED AND CANNOT CONNECT TO SERVERS

Electrum in Tails cannot connect anymore to Electrum servers.

The version of Electrum in Tails is vulnerable to a phishing attack that tricks people in updating to a malicious version of Electrum which is not distributed from the official Electrum website.

You are safe unless you try to do the malicious update manually.

To prevent this phishing attack, all trustworthy Electrum servers now prevent older versions from connecting to them.

Unfortunately, newer versions of Electrum are not available in Debian and cannot be integrated easily in Tails. Given the lack of maintenance of Electrum in Debian, we are still assessing what is best to do in Tails.

Until then, your wallet is not lost and you can restore it from its seed using an up-to-date version of Electrum outside of Tails.


There are some instructions for getting version 3.3.4 to work with Tails here: https://blog.thestever.net/2019/02/26/upgrading-electrum-on-tails-to-3-3-4/

Where did you get that link?
That's a "temporary" fake tor link from bitblenr.io (missing an "e") site reported here: https://bitcointalk.org/index.php?topic=5127439.0
You've been scammed.

Refer to my signature for the real bitblender drop site with the correct tor url.
