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“. ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/e/b/eb20c82652a1c8dcbf59bc05faadc852748af30e.jpeg) 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: ```yaml org.apache.cxf.interceptor.Fault: XML_WRITE_EXC at

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

For me it was the same. App version 2.4.54 I solved it correcting the URL and remove the port and activate “Always send credentials” URL: [https://myopenhab.org](https://myopenhab.org) (without port) Password: Always send credentials: activated Hope that works for you as well. Regards ---
