IOS app error: URLSessionTask failed with error

Hi all,

I have a problem with the iOS app on both iPhone and iPad. I keep getting the error „URLSessionTask failed with error: Timeout“.

I can access my basic ui sitemap via the web but the app doesn‘t work anymore. I tried to play around with the settings: Change graphics PNG/SVG, clear the image cache, send credentials on every log in. And I installed the beta app on the Ipad.

I wonder if there is an error on my server side that is causing the timeout. How would I be able to find out?
I am running OpenHAB 3.3.0.M3 on a Raspberry Pi 3B+. The iOS app version is 2.4.47.

Any ideas how to fix the error? Best, Max

EDIT:
I guess this might be the corresponding log entry:

I also see what I think is the same error message (in English) along with an interceptor fault in the log. These may be related:

Hi @BigGeorgeTx,
thank you. Yes, looks very similar to my error. Good to know I am not alone. :wink:
But I guess nobody has found a solution yet, right?
Best, Max

Same for me since the last some days.
I also use app version 2.4.47.

I also uninstalled the app and installed it fresh, did not help.
