Struggling to authenticate

[stealthybox]

Hello, friends.
Is this IRC gateway still working?

Using both Colloquy and irssi, I was unable to authenticate using TLS /w irc.flowdock.com on port 6697.

I made sure to remove whitespace and strange chars from my password.

I tried setting the server_password to [email protected] pa$$w0rd.
Messaging NickServ with and without quotations surrounding the args didn't seem to work in both clients.
I also tried substituting my personal API token for my password using both methods, but that didn't seem to work either. (https://flowdock.com/account/tokens)

I'd appreciate any pointers on this one -- cheers. 👍
