No database queries are possible in the Selfnet WLAN at the moment. This means that no new devices can dial in at the moment. We are working on the problem
We had another issue regarding database reachability which is fixed now. You should be able to connect to Selfnet Wifi again.
The database problem is solved Devices that now reconnect to the WLAN (the easiest way is to restart devices once) have a working connection again.
