Dear sirs,
I am adding HTTP SSL expiry seniors on several web servers. However, some of the servers getting error message "Protocol Error: Unable to connect to the remote server (code: PE023)" on PRTG Enterprise console.
Actually, I found the senior is located at \PRTG Network Monitor\Sensor System\SSLCertExpiration.exe, when I tried to manually run it with -u=URL, it returns the message saying "The operation has timed out".
Appreciated that if anyone can give me some help.
Here is the brief information. 1) PRTG version V13.4.7.3532 2) All servers with .NET 3.5 enabled 3) Windows "User Account Control" disabled
