Dear,

48h ago, my Sharepoint online apps suddenly stopped working. I see this error in the browser console:

DevTools failed to load source map: Could not load content for https://amcdn.msftauth.net/meInlineBackCompat.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

It seems that this service: https://amcdn.msftauth.net is unreachable. There is a problem with loading authorizations for my apps

What can I do to solve this? Is this a general problem? I have no on premise servers. Everything is in the cloud.

thanks!

    Hi elbbs-8506,

    Is there anything has been changed before the issue occurs?

    Per my research you could try to uncheck "Enable JavaScript source maps" in developer tools settings.

    Press F12 > Settings > Uncheck "Enable JavaScript source maps".

    Nothing changed before this issue occurred.

    There was an issue recently with the ARM.

    "Microsoft Engineers have determined that Azure Resource Manager (ARM) experienced degraded availability in a subset of regions hosting ARM endpoints".

    Probably it's related.
