Hi Synametrics Support,

Thank you for your reply.

I checked for PEM under $INSTAL_DIR/letsEncrypt/*.*, but I don't know how I can use these files under the QNAP Security/SSL certificate and private key.

I think that I am going to find it difficult to install a Let's Encrypt Certificate automatically for the QNAP and Xeams concurrently.

The problem is this in my opinion:

I have to enable web server on QNAP (so that QNAP does not seize port 80) and change the default port 80 on the QNAP web server to some other port number in order for Xeams to use the http challenge to get a new certificate every 90 days. But this stops the Qnap from getting a Let's Encrypt certificate because now it is not listening to port 80 anymore because I made it available to Xeams.  

Perhaps it would be easier to buy a cheap 12 month device SSL certificate that I can use for Xeams and the Qnap. Obviosuly I would have to have both certificate's formats such as PKS and PEM in order to suit both situations.

I was trying to run my own mail server at home, but it is becoming a real challenge now.

Thank you.

Best regards
