Unable to access the NextCloud instance via HTTPS

ℹ️ Support
1

Nextcloud version : 24.0.1
Operating system and version : Raspberry Pi Buster / Linux raspberrypi 5.10.103-v7l+
Apache or nginx version : Apache/2.4.38 (Raspbian)
PHP version : 7.4-fpm

The issue you are facing:
I am unable to access my NextCloud instance using HTTPS. I am able to do this just fine over HTTP.
The error I am getting is:
“Not Found. The requested URL was not found on this server. Apache/2.4.38 (Raspbian) Server at 192.168.0.103 Port 443”

I do have a Letsencrypt cert applied to the NextCloud instance. I am not interested at this time in making HTTPS access work over the internet but from my local network only.

Maybe you can read some interesting parts of this installation guide. You can there change to version Debian 10. Mabe you missed something.

Thanks. I looked over the article. I already tried a lot of things so I am not sure what’s wrong.
My instance is located under /var/www/html/sitename. In the .config files the paths are pointing to /var/www/sitename. Could this be part of the issue? I’ve already tried modifying the paths to point to /www/html/ but it’s still not working. But why does it work over HTTP with the wrong path in the .config file for HTTP?

Adrian

I think it is only a problem with your Apache2 Virtual host for HTTPS / TLS/SSL certificate.
Search in the internet the correct configuration for Apache2 SSL webserver.

Maybe there is only on path in the apache2 config wrong.

I was able to fix it on my own in the end. Here are the things I did:

  • I removed the .conf file for the SSL settings from under /etc/apache2/sites-enabled/
  • I added ServerName 172.0.0.1 to /etc/apache2/apache2.conf; it is 172.0.0.1 because this is what was configured under /etc/hosts (I had an extra entry for 172.0.0.1 folder_name_under /var/www/nextcloudfoldername)
  • removed the two .pem files and options-ssl-apache.conf file from under /etc/letsencrypt/live/domain_name/ and /etc/letsencrypt/
  • I added a ServerAlias domain_name entry to /etc/apache2/sites-available/main_conf_file_for_http.conf
  • ran certbot again and generated a new cert for my domain
  • https finally working! :smiley:
