SSL not working on my subdomain

Help
1

I’ve installed an SSL certificate but it’s not working.

My domain is:
http://admin.oddsclub.eu/

I ran this command:
I want to enable SSL certificate on this subdomain with Let’s Encrypt in webmin.

It produced this output:
It’s installed successfully but URL not working with https.

My web server is (include version):
webmin (1.930)

The operating system my web server runs on is (include version):
Ubuntu Linux 19.04

My hosting provider, if applicable, is:
contabo.net

I can log in to a root shell on my machine (yes or no, or I don’t know):
YES

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
NO

Hi @parth.parikh

checking your domain via https://check-your-website.server-daten.de/?q=admin.oddsclub.eu you see the problem - Grade Q.

You have already created 4 identical certificates

Issuer not before not after Domain names LE-Duplicate next LE
Let's Encrypt Authority X3 2019-08-29 2019-11-27 admin.oddsclub.eu - 1 entries duplicate nr. 4
Let's Encrypt Authority X3 2019-08-29 2019-11-27 admin.oddsclub.eu - 1 entries duplicate nr. 3
Let's Encrypt Authority X3 2019-08-29 2019-11-27 admin.oddsclub.eu - 1 entries duplicate nr. 2
Let's Encrypt Authority X3 2019-08-29 2019-11-27 admin.oddsclub.eu - 1 entries duplicate nr. 1

So don't create a new certificate, that will hit the limit.

And your WebMin-Port 10000 uses that certificate:

eu
eu926×88 3.28 KB

But your standard port doesn't have a SSL-configuration:

Domainname Http-Status redirect Sec. G
• http://admin.oddsclub.eu/
167.86.100.89 200 0.096 H
small content:
• https://admin.oddsclub.eu/
167.86.100.89 -4 0.116 W
SendFailure - The underlying connection was closed: An unexpected error occurred on a send. The handshake failed due to an unexpected packet format.
• http://admin.oddsclub.eu:443/
167.86.100.89 200 0.087 Q
Visible Content: Login E-Mail Address Password Remember Me Login

Instead, your port 443 sends http content. Checking port 443 with http (instead of https) sends the standard http status 200.

So

  • use your port 10000 and ignore the error (or)
  • configure your standard port 443, so that port uses the existing certificate

PS: Result: It's only a webmin configuration problem, not a certificate creation problem.

(This would be done by always using :10000 in the URL in your browser, like https://admin.oddsclub.eu:10000/)

(This would be done by modifying a web server configuration, or a router or firewall configuration if this service is behind a router or firewall that does some kind of port forwarding or port mapping.)
