Error connecting to some Electrum servers

[jp1ac4]

Possibly related to bitcoindevkit/rust-electrum-client#144.

Some Electrum servers are not working with Liana:

Running lianad with "ssl://electrum.blockstream.info:50002" is working for me sometimes.

[darosior]

It also happens in the settings, where it used to freeze the GUI completely for 180s (fixed in #1277).

[pythcoiner]

tested acinq & setup a ssl electrum at ssl://pythcoiner.dev:50002

every thing looks fine in my nginx logs

[pythcoiner]

we still cannot connect to server using self-signed certificates but i open #1300 for this specific issue

[darosior]

As we uncovered where the issue was coming from, i'm dropping the v7 milestone for this issue. Not supporting self-signed certs (#1300) and having to manually add the ssl:// prefix (#1291) is not ideal but needs not be a blocker for the release.

[nondiremanuel]

Should we merge this and #1300 to not have to keep track of two issues? Do you see any downside in doing that?

[pythcoiner]

i think #1300 address the remaining issue

[nondiremanuel]

I would close this then if you are ok
