Unable to get certificate - Challenge was invalid

[Rene Simons]

Hi,

When I click the Certificates button in the settings tab, I get a "Unable to get certificate - Challenge  was invalid" notification.
The process resolved my IP-address but I don't know if that's done by LE or by my app.

• My server is behind a router.
• The domain name is in the settings tab of the server window;
• In the Certificates folder I found the two <domain>.xxx files
• I have port 80 and 443 open in my router (port forwarding);
• My firewall has port 80 and 443 open for my application;
• I use NO-IP as a DNS for my IP-address (Could this be an issue? It isn't when I have an insecure web-server, port 80 only.)

Any hints in the right direction are really welcome.

Cheers,
Rene Simons
