I've got PRTG running on a dedicated machine and using SSL on port 443. I'd like to use port 80 for something else. I've followed the directions here:

https://helpdesk.paessler.com/en/support/solutions/articles/76000063587-prtg-blocks-port-80-although-i-m-using-ssl-on-port-443-how-to-free-port-80

and here:

https://helpdesk.paessler.com/en/support/solutions/articles/61967-prtg-keeps-using-port-80-for-keep-alive-and-interferes-with-the-web-server-on-80

rebooted and yet PRTG continues to redirect port 80.

How can I fix this, please?

Thanks!

When the registry key NoSSLRedirect is set, PRTG shouldn't forward anymore. Can you post a screenshot of the corresponding registry section (blur out other values)?

Screenshot looks fine - have you tried restarting PRTG once more? Can you try to execute the following in an administrative PowerShell window: netstat -anob | select-string :80

...what results do you get there?

This is what I get (task info in parentheses added by me):

 TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       4 (System)
 TCP    0.0.0.0:8008           0.0.0.0:0              LISTENING       2264 (nginx)<--this is what I want to move to port 80
 TCP    127.0.0.1:8085         0.0.0.0:0              LISTENING       6736 (PRTG Server)
