Hallo, thank you for answering! Yes, the ports was open. I have started the radicale service manually via ssh on the command line.
First I checked with
sudo service --status-all
and the radicale service was off although he was displayed in the box as started, anyway now everything works fine. Also the webinterface to create the address books was accessible.
Tahoe-lafs is also back after i reinstalled the application via ssh with apt but i have a problem with the domain, seems to be 2 times in the configuration like this:
-----Die Tahoe-LAFS Server-Domain ist eingestellt auf mydomain.freedombox.rocksmmydomain.freedombox.rocks-------, i will check the configuration and
I will report when I find out something
