I'm using HAProxy to proxy web access to the PRTG web interface from external locations and for the most part it works well. However in many places the URL is wrong with the internal port still being used. E.g. my external FQDN is https://prtg.mydomain.com and it is forwarded by HAProxy to internalIP:8081
When I perform an upgrade, the notification screen that appears shows and monitors https://prtg.mydomain.com:8081 which doesn't work, the same with the notification emails, all it's links get the the port 8081 appended.
The main website works very well for 99% of the time, and even the Android app has no problems. Just the areas I mention above and probably more suffer this issue. Internally of course using port 8081 is fine, but I am not going to expose this directly to the internet. HAProxy proxies for 6 other internal applications just fine although one or two needed tweaks.
Is there any way to fix this for PRTG?
