Let's Encrypt failing ... need help. Admin that set this up no longer here

We are getting a certificate generation failure when trying to “Generate Let’s Encrypt Certificate” … anyone have any guidance? here is the output from the failure: (I of course xxx’d out any identifying info)

There is no failure in this output.

One option would be to go into the GUI and try and setup a new certificate to see what happens when you try to create a brand new cert from scratch.

so I am still getting Generation Failure when trying to generate a new certificate. This is what it says above the box that contains all the information above:

Please check http://xxx.xxx.net/.well-known/acme-challenge/P2ZsMw96tZv8bPUHeyOODpOIpZkO4qkwyPwwCYMcSl4 - token not available
I am sure we are just overlooking something on our end, but I am stumped
