Hi Justin Jose,
Thanks for responding. I am willing to try anything.
I got the same error message and portal still hanging.
Could you run Portal checker. This will identify issues with a portal.
docs.microsoft.com/.../portal-checker
Hi Justin,
Thanks for responding back.
Yes. I tried running the portal-checker. Everything looks good.
I can run the portal. I can even login and clean the cache.
I just can't open the portal app to make changes.
have you tried in different browsers?
Yes. I have tried different browsers. Even the new Microsoft Edge.
Just no luck with opening the portal app.
have you tried turning off and turning on Portal state?
Just tried your suggestion. Still no luck.
All this error messages that I'm seeing in the browser contains this "has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."
