I have a setup where I have a network with the Nextcloud server and several computers. I have an NGiNX reverse proxy that performs SSL termination for the Nextcloud address and ensures that an HTTPS connection is enforced for parties accessing the server through its domain “nextcloud.server.com”
The issue I am having is that when trying to access the Nextcloud server using its local IP “192.168.1.102” it converts HTTP to HTTPS but the server does not have its own SSL certificate.
I cannot find why it does this forced conversion from HTTP to HTTPS even though I am bypassing the reverse proxy “192.168.1.100”. What am I missing?
