No access to my nextcloud

Hello,
today I have installed Let’s Encrypt on a Ubuntu 16.04 System with Apache2.4 per Certbot for view hours.
Is use this manual. https://certbot.eff.org/#ubuntuxenial-apache
It work fine.

Now after 3-4 hours I doesn’t have access to my nextcloud.
Also 5 minuntes send the dns-client the ip-adress to dns.

If I take a ssl-test that work.

I am a linux newbie and I don’t know, where ist the mistake.

Can anybody help me please.

Thank you in advanced.

Best regards,
Christoph

Hi Christoph,

Did you see any messages in the log files, that might help here?
You are saying, that the website is not reachable, right?
Please check the apache logs in /var/log/apache2/

You still have access via SSH right?
My problem once was, that I was banned by fail2ban, due to some testings that were discovered as attacks by fail2ban. Could this be the same for you?

However, without error messages and log entries, it’s difficult to help.

Hello Schmu,
here are the log files.

Hello,
Now it works!

Why are that?
It works, it doesn’t work?

Best,

Does the server name match the name on the certificate? This needs to match up exactly.

Sounds like a browser caching issue. Try clearing your browser cache. Also, make sure you are accessing the server by one address. If you have multiple, such a domain.ext, and www.domain.ext, put a redirect in so access is limited to only one of them.

Hello,
Thank you for this info.
Do you mean I can use only one webproject on the server?

How can I fix it?

Thank you in advanced!

Best regards,
Christoph

You can use virtual hosting to host multiple websites with different SSL certificates. The exact steps are dependent on your web server configuration. See http://httpd.apache.org/docs/current/vhosts/ for Apache.

You can redirect one url to another using mod_rewrite. See http://httpd.apache.org/docs/current/mod/mod_rewrite.html
