we can not login in sogo since last iredmail pro update that we did. the error that I found:

Feb 03 18:02:45 sogod [3185158]: <0x0x55b0efa23160[SOGoCache]> Using host(s) 'localhost' as server(s)

Checking the sogo.conf and old sogo.conf, both have everything commented with \\ and the unique difference is that the newest on has:

  //NGImap4AuthMechanism = "plain";

also commented.

I tried to follow this:
docs.iredmail.org/upgrade.sogo.combined.sql.tables.html

but it ends in an error:

ERROR: Failed to parse value of OCSFolderInfoURL in /etc/sogo/sogo.conf

Seems because sofo.conf basically has nothing configured.

So, how to make sogo.conf file using iredmail settings? We never touched in sogo.conf file since we installed and eventually did iredmail pro update.
