Load Balancing VideoBridge - Prosody not reachable

Hello,

yesterday i tried to install multible servers with load-balancing.
Jitsi doesn’t load and it seems like my prosody is not reachable from the outside - i have no idea how to go on with this.

Prosody is running:
prosody.service - LSB: Prosody XMPP Server
Loaded: loaded (/etc/init.d/prosody; generated)
Active: active (running) since Fri 2020-04-10 11:18:25 CEST; 5min ago
Docs: man:systemd-sysv-generator(8)
Process: 3963 ExecStop=/etc/init.d/prosody stop (code=exited, status=0/SUCCESS)
Process: 1912 ExecReload=/etc/init.d/prosody reload (code=exited, status=0/SUCCESS)
Process: 3970 ExecStart=/etc/init.d/prosody start (code=exited, status=0/SUCCESS)
Tasks: 1 (limit: 2260)
CGroup: /system.slice/prosody.service
└─3991 lua5.1 /usr/bin/prosody

and it says that it added the port:
Apr 10 11:18:25 portmanager info Activated service ‘component’ on [0.0.0.0]:5347

Errors on SSL/TLS:
Apr 10 11:18:25 portmanager error Error binding encrypted port for https: No key present in SSL/TLS configuration for https port 5281
