SharePoint Page in custom teams app

Question

I've created a custom Teams App to show a SharePoint Site, it worked just fine for a couple of days and all of a sudden it stopped and I only get Timeouts when trying to open it. It works fine in the iOS App but neither on the Desktop App nor in the Web version.

I've added the SharePoint URL and login.microsoftonline.com to the valid Domains, but it doesn't help.

Any advice would be welcome!

Hi, I think I found the Issue, the console says that it can't load the login.microsoftonline.com page because the X-Frame-Options are set to DENY. I understand that it's a countermeasure against clickjacking, but is there a workaround for Teams Applications? Thanks in advance!

Hi, most of it doesn't apply to my application since all of it is hosted by Microsoft, but I noticed an error in my App Registration and now it works in my Browser, but it's still timing out in the Desktop App. I guess it's the cache but I can't find the files of the "New" Teams App on Mac, the Support article doesn't help since it's written for the old version.
