Ipad wont connect to server. error code NSURLErrorDomain -1001

Hi I wonder if anyone could help me, I’m new to home assistant, I had Home assistant running on the iOS companion app on my iPad and everything was ok, then I accidently closed the windows system 32 cmd.exe on my pc (not sure if this caused the problem) but my app on iPad will no longer connect to server, it finds my server automatically but when I go to connect it takes ages then pops up with FAILED TO CONNECT and the Error code NSURLErrorDomain -1001, it was popping up with a red bar at the bottom of the screen with a different error and gave me the option to go in and debug but that didn’t fix the problem, then I decided to delete and reinstall the app but that didn’t fix the problem either, not sure how to fix this one any idea’s much help would be appreciated.

-1001 is a timeout occurring; in other words, the server attempting to be connected to isn’t responding. You should double check the IP address you’re attempting to connect to and make sure it’s the right one for the server, that you’re on the right Wi-Fi network, etc.

This started appearing on my iPhone today. Never been a problem until the most recent HA release. :frowning:
