Letsencrypt issue

I have Axigen X.2.2.75
I followed the document for setting up letsencrypt, it took all the commands successfully. but then in the logs i found it could not create the dir *.mydomain.com and of course it cant create files and it closes connections. I tried this again using the proper MX record mail.mydomain.com and it completes all commands with success, but in the logs it is still trying to create the *.mydomain directory. I have tried stopping and restarting Axigen services since my first attempt but it is still trying to use the wild card as a directory and it cant use a * for a directory name. where is it getting this *.mydomain from? This is a windows server 2016

My exact CLI command i used:
GENERATE letsencrypt hostname mail.mydomain.ca terms yes contact postmaster@mydomain.ca
output is: +OK Issuance Job added successfully

I found the Request file in the letsencrypt folder and removed the *.mydomain reference everything went fine after that.
