Notifications are constructed with wrong URL's

[LayLow]

Hi,

- Community Server (non docker)
- Document Server (non docker)

Community servers FDQN is 'example.com' and host name (local server) is 'server1'

All notifications such as Task or calendar reminders have the wrong FDQN URL as links. All links are to:
server1.example.com

This community server is also running a perfectly working mailserver and its settings are correct set in SMTP setting of ONLYOFFICE.

Any clue please?

TIA

Hello LayLow!
Why and what for do you use "host name (local server) is 'server1'"? You can assign domain name to OnlyOffice portal.
Please describe your issue in details.
