Let’s Encrypt Certificate not trusted.

0 votes


We operate a FreePBX as a SIP telephone system. A new employee has just started. I have installed and set up the current Zoiper client for him on his laptop. When establishing a connection, I received the message that the certificate is not trusted. 

error message


Do you use a separate certificate store in your software? Because the certificate is otherwise accepted by all devices.
