Connection error: Unable to connect to discordapp.com: SSL Handshake Failed.

I get this error when connecting: Connection error: Unable to connect to discordapp.com: SSL Handshake Failed.

What version of Pidgin are you using? If it's not the current latest (2.13.0) then you'll want to use the NSS Preferences plugin to change the TLS max version setting until it works

failing that, attach a debug log (from the buddy list, Help->Debug Window) as you reconnect to the account

I have just compiled purple-discord and try to use it as a Spectrum2 gateway backend … and I get the same error. Here are the lines from the logfile:

According to the startup message, TLSv1.0 (0x301) - TLSv1.3 (0x304) is supported and allowed:

this is also affecting me. latest version of pidgin isn't in Ubuntu repos yet, but using the NSS Prefs plugin to change Max TLS version to 1.2 (down from 1.3) did indeed help. attaching error log here anyway, in case that is still of any use to you. https://gist.github.com/mindcombatant/8fc323e4ce4c02f2425b642c3341b02c

@EionRobb Do you know how to set max_tls with Spectrum2's [purple] section?

Getting this as well with 2.12.0:

Couldn't connect to gateway

(09:57:20) proxy: Connecting to gateway.discord.gg:443. (09:57:20) proxy: Connected to gateway.discord.gg:443. (09:57:20) nss: Handshake failed (-12286) (09:57:20) connection: Connection error on 0x55e677102e70 (reason: 0 description: Couldn't connect to gateway)

Will try with 2.13...

Updated: updating to 2.13 resolved the issue for me.

I had also same issue while using Pidgin 2.12.0 from LM repos. Using 'NSS Preferences' plugin and changing TLS max version from 1.0 to 1.2 solved it.

Same here with bitlbee

Today this problem surfaced for me too, using the nss preferences plugin and setting the max version of TLS from 1.3 to 1.2 solved the issue. Yesterday I updated nss from 3.57 to 3.58 on Artix Linux, which may be why the problem surfaced.

This new issue I found may be related to #313.
