I used a internally issued SSL Certificate on my PRTG Server for years. Had the iPadOS App running, accepted the SSL certificate back then and all was good. Recently, the SSL Certificate on the PRTG Server was renewed/replaced (before it expired) and all is good (website works fine) but the App on my iPad complains about the new certificate being untrusted. Normally, you say "accept anyway -> yes" and then it should be good. But the error message keeps popping up every 15 seconds. It drives me crazy.
I uninstalled the app and all related data and re-installed the app from scratch. Still complains every 15 seconds. Uninstalled, power-cycled the iPad, re-installed again. Still same problem.
I tried to find the certificate in the device's certificate store, looked at its root certificate store (it hold the still valid root CA certificate from the internal certificate authority). This is all a bit cumbersome on iPadOS.
How can the iPad App and I become friends again? I needs it to respect my "yes accept the new certificate" permanently, instead of forgetting about it 15 seconds later (It acts like a goldfish :-)
Kind regards, Steve
