SASL+TLS leads to connection failure about matterbridge

[42wim]

Could you paste the crash ? I'm using TLS+SASL myself without any issues (on freenode)

[42wim]

I've added verbose debugging of the IRC bridge connection when you enable debug. You can now debug SASL and compare it with and without TLS. It should be exactly the same though.

The gateway now also when a bridge fails to startup. So no NPE anymore.

[ishitatsuyuki]

hmm, the NPE disappeared, but no debug log is shown. I have no idea it's broken.

[42wim]

You did run matterbridge with -debug?

[ishitatsuyuki]

Sure.

[42wim]

Could you paste your config?
And the full debug output you are getting now.

[ishitatsuyuki]

Wow, figured out now. It was the IRC port settings. No debug output there, though.
