Hello dear community,
I currently have a small problem with Collabora or I can’t find my error.
I have a newly set up Nextcloud instance (everything worked here without any errors).
This has now been refined a little using a custom theme and connected to the Internet via Nginx reverse proxy manager. I also had some initial complications here, but I was able to resolve them relatively quickly. (I followed these instructions: https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/reverse_proxy_configuration.html → I had to set overwrite.cli.url and overwriteprotocol here).
Since then the cloud has been running quite well. It also passed the test run.
But now that other friends/acquaintances also want to use the cloud (and Office here too), Nextcloud Office was the obvious choice. (In this case with the Build-In CODE Server)
My Probelem:
The server is accessible purely via https, but the CODE server always wants to use http://[SERVER_URL]. This of course leads to a security warning in the client browser (which is good) and if the client “clicks away” this warning, my reverse proxy rejects the http request.
Unfortunately, after a long search I couldn’t find anything that exactly applies to my problem, so I opened a new topic here. I have not found anything about whether it is possible to change the settings so that it uses https://? etc.
Thank you very much for your help
About my setup:
Proxmox Server contains 2 VM´s → one is the reverse proxy and one is the cloud-server
All VM´s are on a seperate 192.168.200.0/24 Network.
On the Reverse Proxy is Nginx Proxy Manager (NPM) installed.
IP of the Proxy: 192.168.200.6
(Sadly the forum dont let me post more than 2 pic´s in my first thread so i have to text out my npm config)
Under “Details”:
Domain-Names: [domain_to_my_nextcloud.de]
Scheme: http
Forward Hostname/IP: 192.168.200.108
Forward Port: 80
Cache Assets: No
Block Common Exploits: Yes
Websockets Support: Yes
Publicly Accessible
Under “Custom Locations”:
Location “/”: http - 192.168.200.108 - 80
Location “/.well-known/caldav”: http - 192.168.200.108/remote.php/dav - 80
Location “/.well-known/carddav”: http - 192.168.200.108/remote.php/dav - 80
For all Locations i have following additional headers configured:
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
Under “SSL”:
SSL-Certificate → [domain-name] (it´s a Let´s Encrypt Cert Autogenerated)
Force-SSL: yes
HTTP/2 Support: yes
HSTS Enabled: yes
HSTS Subdomains: no (because i have no subdomains)
Under “Advanced” there are some timeout parameters like “proxy_connect_timeout” etc. but they are not intressting.
Setup of the Cloud-Server:
Ubuntu 22.04 Container
IP: 192.168.200.108
Apache2 Webserver
Nextcloud install located in /var/www/html/nextcloud
The Apache2 Webserver Root is the same directory. Also the Apache2 Server only listens on Port 80 because the Reverse-Proxy handles all the SSL-Stuff
