I'm having issues with my tab app when trying to open it with deep link. I'm simply using the link provided by the tab context menu (copy link to tab) and opening it.

When trying to open it in Chrome or Desktop Teams app I'm getting:

There was a problem reaching this app

In dev tools console I can see multiple failed reason: AppInitTimeout logs.

Looking at network activity I can see that actual request to get the tabs got cancelled:

I've also checked my server access logs and there is no trace of the browser trying to access the app.

What is strange is that the link works correctly on Safari. The app opens just fine when I'm accessing it from the tab menu.

I've run out of ideas how to debug it further, any ideas what could be wrong here?
