Electrum won't connect to EPS anymore #192

Open otaviobonder-deel opened 4 years ago

otaviobonder-deel commented 4 years ago

I had EPS and Electrum working for a while. Everything was working fine, however the Electrum stopped connecting to EPS. Already tried to reinstall both Electrum and EPS, and the problem persists.

I connect Electrum to EPS by Tor. Tor is running on both machines, server and client. EPS is configured to listen to 127.0.0.1:50002 and on the server the Tor is listening port 50002 and routing the connection to 127.0.0.1:50002, so it's configured right.

EPS log shows it's listening:

However Electrum can't connect to it:

On another server I have Electrs running over Tor as well and Electrum connects fine. I'm not sure what's causing this issue

Thanks for the issue.

Do this: run electrum with the command line argument -v, then go the Qt console and type network.debug = True. Then you should get lots more debug information on the command line. Hopefully that will provide more clues.

This is the log from Electrum:

I'm getting the same, running EPS version 0.1.6. Bitcoin version 0.21.2.0 and Electrum version 4.1.5.

Electrum shows red dot for network connection.

Thanks for the report @realSConway

SOLVED (at my end): upgraded EPS version 0.2.2 (I was on 0.1.6)
