In my version of Kontalk 4.0.3 (326) (F-Droid) that date of the serverlist is sept 4Th 2016.
Is this correct?
If I try to update this serverlist is taking ages and gets me no where.
The server list hasn’t been updated for some time so that’s correct.
About taking it ages, can you send us a debug log of the attempt (settings > maintenance)?
