Incoming Webhook app on Teams is not working/posting notifications since 14/04/21

Hello everyone,

It seems like suddenly the URLs from the Incoming Webhook App (see image attached) on Teams has stopped working for me. I updated the URLs to the new format as required about a month ago and everything was working fine until this week when the notifaction cards stopped working.

I am using the webhook URLs in GitLab to post updates in a Teams channel. Testing if the URL works shows a message "Testing failed" which means that something went wrong with the ability to pass on the notification to the URL.

Just opening the webhok url on the browser shows - invalid webhook request - get not supported - as an error.

I even tried setting up a completly new URL in the app and even that shows the same error. I tried using the web version and i got the same result after using the URL from the web version of the app. I also tried manually pushing a test message using curl commands on powershell, this did not work as well. All the URLs i tested new updated and old dont seem to be working.

Any insight on this issue would be great! I really cant put a finger on where the problem lies and after lots of googling it seems like nobody else has faced this problem for now.

Best Regards

Hi. I had tried pushing a notification using powershell without errors but to no effect. I did not know about postmaster so i didnt check that.
