TLS (SSL) certificate problem

The TLS (SSL) certificate has a problem: The certificate has expired or is not yet valid. It is valid from 2018-05-20 01:01:27 to 2018-08-18 01:01:27.

Has anyone seen this or know how to fix it?

my domain is and is setup using I recently upgraded which I think is the issue as its been working flawlessly for years.

Thanks in advance

Got it in my box too.
Certificate has a problem: The certificate is expiring soon: The certificate expires in 2 days on 08/26/18.
Tried to Provision, got:

return config.func(config, plugins)

raise errors.MissingCommandlineFlag(msg)

tried to give cetbot the agree via:

certbot --agree-tos -m MYMAIL@DOMAIN


Certbot doesn’t know how to automatically configure the web server on this system. However, it can still get a certificate for you. Please run “certbot certonly” to do so. You’ll need to manually configure your web server to use the resulting certificate.

well got it in other topic :slight_smile:

Had this same issue, and none of the fixes worked.

I was able to resolve it by manually editing the /root/mailinabox/management/ file and adding the following two lines on line 334:

"--email", "", # use your email here

So it ends up looking like so:

Save the file and re-run the script using ./

Once the SSL certificate is successfully provisioned, you can remove the two extra lines you added.
