I recently installed Nextcloud using the snap package on Ubuntu 16.0.4. Due to my ISP provider I had to change the default ports to 81 and 444, I want to enable https with a certificate, since self-signing gives continuous warnings. However, after some research it does not seem the let’s encrypt can work with anything other than port 80 and 444. Is there a way to setup https with a certificate on a different port?
also I have had to manually type in the port and https in my browser window for it to connect properly, is there a way to fix that
I am sorry if this question has been asked, I could not find any answers and I am very new to linux, nextcloud, and web servers as a whole.
