Topic: Electrum 4.0.2 keeps Synchronizing (Read 200 times)

Can confirm... I had a similar issue until I updated to Electrs 0.8.5... it was the "fee return" error patched here: https://github.com/romanz/electrs/commit/e55381fa6643661c0dad2c454415ed997084a13d

Without it, the client just keeps disconnecting/reconnecting. Once you update and restart electrs, it should start working properly again.

Thanks! I'll try that.

Seems to be an issue with your server not returning the fees. This was an issue that was reported a few days prior.

You need to update your Electrs to 0.8.5. The newest update fixed this, as specified in their changelog.

oops this is the complete error section from the log:

electrum.interface.RequestCorrupted: required field 'fee' missing from dict

So here is the error logged, the rest look fine to me:

I'll look at the logs as soon as I am back home. Thanks.
The weird thing is that it was working perfectly before the Electrum 4.0.2 update and just after until I broadcast the first transaction (moved a specific coinjoined coin to HW)

Yes I am running Electrs and until the update it worked perfectly.
It still connects and it seems it is synchronizing but after reaching the  314/314 it starts all over again...

The moment that you've seen a server message means that you've just connected to that server.
It's displaying that message in repeat because you've been connecting to and disconnecting from that server again and again.

There's probably something in your client that keeps booting you out of the server.

Your logs (%appdata%/electrum/logs) should provide sufficient info about the issue (Enable in: Tools->Preference->Write log to file).

Are you running your own server? What happens with the previous version of Electrum? Does it connect flawlessly to that server?

Try changing servers?

Click the bottom right bubble, uncheck select server automatically and right click a server and click use as server.

Hi!
I just updated to Electrum 4.0.2 on Ubuntu connected to Electrs 0.8.3.

After broadcasting correctly a transaction from an imported Wasabi Wallet, it gets stuck in an endless loop "Synchronizing... (n/314)" over and over.

The console shows an endless:

  Welcome to electrs 0.8.3 (Electrum Rust Server)!
  /Satoshi:0.20.0
  >>

I had no problems before the update and nothing else changed but Electrum.

Any idea?

Thanks!!!
