Open Source Document Management System | OpenKM

I have an own eMail Server, MailStation2 (Synology DiskStation)
I tried to access it by IMAP(143) or IMAPx(993) both without success!

with IMAP I got: Couldn't connect to host, port: myServer, 143; timeout -1
with IMAPx I just got the error: "connection reset"
I found nothing with the search string OpenKM "connection reset"

User, password and ports and protocol are the same like I use successfully in my local eMail Client
Firewall was open.

(I tried also to access my web.de eMail account with success)

Any idea

Thank you in advance!

Try to ping "myServer" from the openkm server. May be will be better using the IP either the server name. What seems clear in error advice is that you are not being able to get connected to the server, because you are receiving a time out. That is not something what may be solved from openkm side, should investigate why you are not getting connection ( networking, dns issue, firewalled ... )
