Can I please request a TLS 1.0 fix?



Your Vote:



Hi there,

We are working towards disabling TLS1.0/1.1 on our environment. We've disabled it on windows registry, but PRGT still communicates on older versions. I was advised that there's a registry fix for this. Could you please send this fix to us?

Dear narayanadhikari,

regarding the TLS 1.0 communication, which port does PRTG use here? If it is 23560 which allows 1.0 connection, that would be for the probe connection. The web server however (port 443) should no longer accept it. Is that the case? The registry hack only affects the web server.

However, the upcoming 18.3.44 will allow to disable TLS versions through the interface, including for the probe connection.
