Nextcloud login page gone after ubuntu update

ℹ️ Support
,
1

Nextcloud version: Nextcloud 20.0.14
Operating system and version: ubuntu 24.04.1 LTS
Apache or nginx version: apache 2.4
PHP version (eg, 8.3): PHP 8.3.6

The issue you are facing:
We just upgraded Ubuntu to 24 from 20. We got a new https cert with certbot. We then tried to copy the config folder, theme folder, data folder, and database to the mounted backup drive. Well in the process I messed up something and now the Nextcloud login page is gone!

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. my https:// url gives me “Not Found-The requested URL was not found on this server.”
  2. my local ip brings me to the apache ubuntu “IT works page”.
  3. http url is a blank page

we’ll need to know exactly what happened.

Don’t panic!

[!IMPORTANT]
Relax, take a deep breath, get a cup of tea and consider your options. Recollect steps taken, note recent changes and structure that information. Do the basics and try to get a grasp of the situation.

If you’re having a Nextcloud snap issue and you’ve come this far, then you’re on the right track!

  1. Ensure nothing was missed:
  2. Run the debugging script before raising an issue
  3. Create an issue and complete the bug report (the more information the better)

It was working fine before i tried to use certbot to recieve a new cert. I believe my issue could have stemmed from using “sudo certbot --apache” rather than running certbot in the nextcloud snap. When i did this it issued the cert but httpd was running on port 80 blocking the certbot from completing. Then it was stopped by port 443. I thought well why not open port 77 http, 80 for apache, 443 for https on nextcloud. It seems 8pids were running for apache when i run the grep command to list.

yip… thats it! See Managing encryption and HTTP/HTTPS port configuration as well as Reverse proxy configuration and 101: reverse proxy

if you’re running multiple services a reverse proxy would be your best option. Nextcloud snap encryption will not work on port 77 as Nextcloud snap automated encryption requires port 80 and 443 for lets encrypt certification. alternatively put apache on port 77 and leave the snap on port 80 and 443…
