Docker Compose Jitsi is not working when OnlyOffice is installed

H!

I want to install OnlyOffice (a OpenSource Groupware) and Jitsi all trough Docker on my vServer and make them accesible trough subdomains with nginx. Each one installed individually is behaving without a problem, but as soon as I try to install the other one, someting goes wrong.

For example: This time I installed nginx first - assigned SSL trough Certbot, installed OnlyOffice with Port 280 assigned to 80 and 4222 assigned to 5222 (for Jabber Chat), routet the main domain to Port 280 trough Nginx and everything worked like a Charm. But as soon as I start to install Jitsi, I get this:

ERROR: Encountered errors while bringing up the project.

Has anyone a clue how to fix that? I thought it was cause XAMPP uses Port 5222 to communicate with Jitsi and OnlyOffice uses the same Port, but as assigning the Port to 4222 in OnlyOffice does not seem to solve the Problem, I dont know how to solve this issue and I dont really understand the Error Codes either.

Thx a lot!
