1.26.0 connection failed EOF while 1.25.2 works with same config

[Bastrabun]

Describe the bug

Using matterbridge-1.26.0-linux-64bit and this config

[irc.tv]
Password="mytokenwasreplacedofc"
Nick="Somenick"
Server="irc.chat.twitch.tv:6697"
UseTLS=true
RemoteNickFormat="<{NICK}> "
Charset="utf-8"

I get this error:

time="2023-04-04T11:26:18Z" level=error msg="disconnect: error: EOF" prefix=irc
time="2023-04-04T11:26:18Z" level=fatal msg="Starting gateway failed: Bridge irc.tv failed to start: connection failed EOF" prefix=main

Downgrading to matterbridge-1.25.2-linux-64bit does not produce the same error

To Reproduce
Use the config above for matterbridge-1.26.0-linux-64bit

Expected behavior
Matterbridge connects to Twitch

If necessary I can bring more or set matterbridge into a debugmode of your choice.

Environment (please complete the following information):

• OS: debian testing
• Matterbridge version: version: 1.26.0 6dafebc
• If self compiled: N/A

Additional context
Workaround available: Downgrade to matterbridge-1.25.2-linux-64bit: version: 1.25.2 20f841c
Not urgent
Selfcontrolled, we can do all kinds of tests with it

For my reference 4114

[42wim]

run with --debug please, but there are no irc code changes between 1.25.2 and 1.26.0
They should behave the same.

Here you can see a successful join to irc.libera.chat and then starts the join to twitch.

Thanks, can you do exactly the same with 1.25.2 where it has no issues? (and paste it here)

[Bastrabun]

We start at the same line like above, in a successful join to irc.libera.chat

ooc: I see a couple of channel-specific values - none of those are secrets, tokens or can be used in a hostile way? I took a look through the stuff and while I didn't find anything obvious, I have a hard time figuring out what's better kept a secret.

[42wim]

if your password isn't there there shouldnt be any other secrets for irc

[42wim]

Do you know how to build matterbridge yourself?
The only change in irc is in the irc library itself lrstanley/girc@8240917

If you clone matterbridge from master, revert that change above in vendor/github.com/lrstanley/girc/conn.go and do go build -mod vendor you should have a matterbridge binary with exactly the same version of irc as v0.25.2

[Bastrabun]

I built current master 89b0d36 and the 1.26.0 tag https://github.com/42wim/matterbridge/tree/v1.26.0 , both without the commit indicated in your previous message. In both cases it connected to twitch irc without problems.

[42wim]

ok so there's not really an issue? seems like something wrong with your debian build only

[Bastrabun]

If the error appears with the commit lrstanley/girc@8240917 you mentioned and the error does not appear without this commit, this indicates this commit is responsible for the problem.

[42wim]

ok I misread, could you open an issue on https://github.com/lrstanley/girc/issues ? needs to be fixed upstream

[Bastrabun]

Upstream issue: lrstanley/girc#62
