Unable to log in to PRTG after disabling SSL

I have PRTG fully configured and working, now I just need to disable SSL so I can get integrate it with my reverse proxy via NGINX. However, once I disable SSL, my username and password no longer work. The logs indicate an "anonymous" account was used to log in.

Example:

  1. 348270 2021-03-09 19:05:48 192.168.1.5 "anonymous" 192.168.1.3 2548 GET /systemsetup.htm tabid=1 200 "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0"

Re-enabling SSL lets me log in again, but that doesn't help me.

Has anyone else run into this before?

Hello,
SSL can be disabled at "Setup > System Administration > User Interface". This article might be of interest as well.
Disabling SSL shouldn't have any influence on the user login and I couldn't reproduce this issue with the latest PRTG version 21.1.66. Which PRTG version are you using currently?

I'm using version 21.1.66.1623.

I've disabled SSL via "Setup > System Administration > User Interface", and enabled via the PRTG Administrator.exe as I am unable to log back in via the web interface.

Is there an error message displayed while trying to login using the Web interface? If so, could you send us a screenshot to [email protected]?

In addition please also send us a "support bundle" containing the log files from PRTG, so we can take a closer look. For this, please open the support dialog "Contact Support" in the lower right corner of the WebUI.

Kind Regards,
