Am I supposed to see an "Apache2 Debian Default Page" when I open your site? Is the IP address of your site ( correct?

Hi, Osiris

No, the service I installed was nextcloud. It's not the web suppose to work. If you open my site with IP address you can find nextcloud page " Access through untrusted domain".

Yes, this is the IP address.

I found two links in /etc/apache2/sites-enabled about ssl. One is nextcloud-le-ssl.conf and the other is default-ssl.conf. I removed default-ssl.conf and it works again. I hope that was the right solution. I don't know how this link was there.

Sometimes a good question is better than a good answer. Your's one, of course.

Thank's. :wink:


I've seen this before unfortunately. For some reason Apache gets two configuration files biting each other.. I think it's all good now.
