bitcoin core slow sync today?

[gabrio81]

hi guys,

I've launched core this morning on 99.74% and it's still there after all day, are there some issues? I see 0 active connections to bitcoin network...

thanks,
gab

Can you post your debug.log there looks like there probably is an issue.


It'll be in the data folder for bitcoin core, either C:\users\username\appdata\roaming\bitcoin, C:\users\username\appdata\local\bitcoin or ~/.bitcoin depending on your operating system (if you didn't set a custom difrectory).

Unless you can post today's stuff then yes.
you can use pastebin https://pastebin.com/ to put it up.

What does it say at the bottom of the screen next to the loading bar?

Is is saying that it is syncronising with blocks or "no block source avaliable" etc...

So it's sticking on connecting to peers according to that, do you have any new firewalls that could be blocking it (or your ISP) although it's not even loading up the list of peers that they normally have...

nothing new really... I tried to use a proxy just earlier but no difference, I can see that there is network traffic, like 3MB... this is very odd.. on another forum someone suggested to delete the latest blk and rev file.. what u think of that? thank you

If you do that it'll reindex your entire blockchain.

How long did it take to sync, as it'll do all of that again?

I'd sooner suggest booting your computer in "safe mode with networking" and run your bitcoin core to see that it definitely isn't a firewall issue.

In safe mode now and it seems exactly the same... teued to get connections for a bit then blinks then off again.

The whole chain? Well im on a 17mbit connection.. that will be long.

Any other ideas?  Oh actually the pc went to standby when i was home without shutting down the core client .. laptop ... altho that happened before.

Thank you

It won't redownload the chain it will run back through it but it will still take quite a long time to do that.

If by standby you mean hybernate then that shouldn't be the cause of the issue.

I'd suggest waiting between a few hours a day for someone who can work out the exact error in the debug.logs that you have provided as they should be indepth enough for someone who knows more about the source code of bitcoin core.

Right that makes sense.....now deciding whether doing that re-download thing (if that is at all a viable option) or doing something else... in that case.. ANY EXPERT around???


thanks for all your help jackg anyway!

Give them 24 hours to come here and then try reindexing (deleting the last blk file).

It won't download everything again unless it finds an issue but it will have to scan through it all and reindex everything.

[achow101]

The problem is that your node is rejecting block 533816 which means that any node which attempts to give it that block or any of its descendants will be disconnected from immediately.

Open the Debug Console (Help > Debug Window > Console) and then enter this command: reconsiderblock 0000000000000000001f642d24d3968eeef81460531346adbfb9882dd711ed45. If it returns with null, then the block was accepted and you should be able to connect to nodes and sync the rest of the blockchain.

Otherwise, start Bitcoin Core with the -reindex-chainstate option. That will reindex the chainstate (not quite as bad as a full reindex) and that should also fix the problem.

If all else fails, deleting the most recent blk*.dat and rev*.dat files and then starting Bitcoin Core should work too. That will trigger a full reindex as well as redownload the most recent blocks.

thanks a lot, actually I did the "deleting the most recent blk*.dat and rev*.dat files", it took 2 hours and 30 minutes for the database, now doing the "processing blocks on disk" and seems to work......I reckon other few hours for this round and let's see...thanks!

hi guys

it seems to have worked, it was syncing all day, now left at 25 weeks behind, so far so good... hopefully also the newest transactions will work OK
