Hey there,

since the 5.6.0 upgrade I'm stucked in a login loop when I try to use Sogo.

I already dropped the table "sogo_sessions_folder / restarted sogo as mentioned in the new Headup (https://forum.iredmail.org/topic18966-h … e-560.html).

The sogo log shows me:

May 05 16:46:40 sogod [831623]: <0x0x55f0d82c8ca0[SOGoCache]> Using host(s) '127.0.0.1' as server(s)

and the nginx error log:

5748 connect() failed (111: Connection refused) while connecting to upstream, client: 40.101.xx.xx, server: sogo.online.net, request: "POST /Microsoft-Server-ActiveSync?Cmd=Ping&User=xxx%40online.net&DeviceId=0f773ddcd04b44fe5729de&DeviceType=Outlook HTTP/1.1", upstream: "http://127.0.0.1:20000/SOGo/Microsoft-S … pe=Outlook", host: "sogo.online.net"

Any hints on that. Maybe anyone else with the same problems?

Greets and Thanks, Mike
