Miraculously, I don't get that Error 461 anymore. I have no problems at all if I connect directly to freenode.
ATM, I have the problem that if I connect to my bouncer (ZNC) that provides playback for 2 channels, the app hangs upon connecting ...
I 'm under the impression that it generally get's worse when I'm connected over wifi. No open mode, inception or off-wall tweaks here.
Edit: Also, the app does not establish a web-connection on its own, has to be done manually before.
