Trying to request a certificate for one of my sites I run Virtualmin for my hosting platform on a Debian 9 install.
I have 2 SSL sites my blog drguild.moip.me which works with certificates and my community forum cajgo-support.com which has is the main site and a forum at community@cajgo-support.com
In virtualmin the certificate is held by the top site cajgo-support.com and community is a sub server managed by the parent.
When requesting a certificate for the community site and forum in virtual this error shows:
Requesting a certificate for cajgo-support.com, community.cajgo-support.com from Let's Encrypt ..
.. request failed : Web-based validation failed : Failed to request certificate :

The certificates were working, but I switched from Centos 6.9 to Debian 9 to rebuild the server and since I am getting errors requesting a new certificate.
My current certificate info is as follows.

I have a test file in the acme-challenge folder which can be read so the folder can be accessed.
I don't know what needs to be changed as I haven't changed any settings backend in No-IP and I backed up and re-imported my server to Virtualmin.
Only thing I can think of at this stage is to wipe the forum server sub vhost and create a new one importing copying back the the web files and mysql database to get a new virtualmin config.
But I would rather fix the issue than to do that.
The error is only on the forum sub server and not the parent cajgo-support.com which shares the same certificate.
