i installed under Nextcloud 220.127.116.11 the Onlyoffice connector App.
I followed this instruction to build a working docker community document server reachable under port 8443
I have installed ufw and remarked problems after upgrade to ONLYOFFICE 7.1.0 so made some investigations and found this information
i set ufw allow from any to <ip-address-of-github.com>
from that beyond saving the ONLYOFFICE settings worked again.
Now my test form LAN, everything ok, creating new docs / changing existing docs all good.
From my Work i tested as well and get “ONLYOFFICE temporarily not available, please contact Administrator”
Testing https://MY-NEXTCLOUD-FQDN:8443 delivers “blocked” (Connection refused)
I have to mention, that for the moment i opened the portforwarding 8443 → to local IP:8443 of my nextcloud server directly because i can’t get it working with my existing reverse proxy.
I tested the same address from mobile device with SIM card → working, port 8443 is reachable.
At work port 8443 is blocked.
My Nextcloud is behind a reverse proxy that support delivering my nextcloud instance under port 443. This standard https port isn’t blocked by Workplace IT. So nextcloud is reachable.
I can’t run docker image under port 443 as well because already in use by nextcloud.
So which reverse proxy settings do i need (nginx server) to deliver traffic from 443 to ONLYOFFICE docker?
And second question how can i get it working as long the url in the nextcloud app ONLYOFFICE settings is named https://MY-NEXTCLOUD-FQDN:8443 ?
(https://MY-NEXTCLOUD-FQDN:443 is not possible because same address as nextcloud server itself)
