GUI freezes upon inputing unreachable Electrum server in settings of bitcoind-using Liana wallet

Testing Electrum support by switching my Liana wallet to Electrum, if i input an incorrect or unreachable server it just freezes the GUI.

Some logs. It can connect but it fails to talk to it. It's because i'm missing the ssl:// prefix, so it probably tries to speak in clear to it.

Seems like it would be fixed by your idea of pinging the server in the dummy client to test the connection.

@nondiremanuel i think we can close this as the switch feature have been disabled?

There can be a point when we will enable the switching feature, but you are right that it's not an issue relevant for now. I will just add a reminder in #1335 to check for this case when we will implement it and close this.
