Any known problem OFTC-Chat (irc.oftc.net) over Tor (using Whonix 10.0.0.5.5)?

Is any known problem on OFTC-Chat?

Since Thursday the last week I am having connectivity problem with the OFTC chat-service over Tor (using Whonix 10.0.0.5.5): It worked fine till Wednesday.

irc.oftc.net/6697

and/or

irc.oftc.net/9999

both do not work any longer.

Please any known reason?

It’s a known problem. We need to find another IRC network, that is Tor friendly.
