Fine tuning questions


I have set up mailinabox and have it accepting mail and so on.

I have problems in a few areas. And it would be wonderful if someone may have some ideas.
Firstly using the provisioning tool for TLS

Something unexpected went wrong: The HTTP Validation challenge for xxxxxxxx failed: Could not connect to …

Reading account key from /home/user-data/ssl/lets_encrypt/account.pem.
Validating existing account saved to /home/user-data/ssl/lets_encrypt/registration.json.
Reusing existing challenges for xxxxxxxx
Validation file is not present — a file must be installed on the web server.
Requesting new challenges forxxxxxxxx
Validation file is not present — a file must be installed on the web server.
Reusing existing challenges for xxxxxxx
The HTTP Validation challenge for xxxxxxx failed: Could not connect to xxxxxx

Secondly I get an error when I check the status from the drop down menu.
the only syslog errors;

Should I run the installer again?

Thanks in advance

That could be an option. But are you running the system on Ubuntu 14.04? And dit you manually remove some package, because at least UFW gives an error.

can you manually run “sudo ufw status”
