MyQ garage door opener

I had the same problem when I upgraded to the iPhone 15 yesterday. Naturally I went all over the internet looking for answers that’s how I found this thread then I looked up a YouTube video called “MyQ App Error 122: How to Fix MyQ Garage App Error 122”. It gives a couple of solutions to fix the problem but the only one that worked for me was deleting the app the reinstalling it. The app started working just fine afterwards

Contact MyQ directly. Apple doesn't own them.

I have the same issue (iphone X and ipad Gen5). Receive the same error when I try to login on the MyQ app. Tried to delete app and reinstall. Tried on cell network only connection. I do not use VPN. And multiple other things chamberlain suggested And their final solution - it’s a cloudflare error indicating my device is not secure and to contact Apple. I need to find out what Cloudflare determines is secure. I do not think Apple has anything to do with it. Hopefully this may help others.
