We have been using SSL Certificate Sensor for number of websites/domains and it was working fine for years until I moved some of them to Cloudflare for DNS (SSL/TLS encryption mode is Full (strict)).
I'm getting this error message now (PRTG version 22.1.75.1594 ):
Failed to establish secure connection

[Step 5] Error connecting with SSL. Error connecting with SSL. error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol
Is there something I can do to get this sensor working again?
