Slack contact points failed

Hello,

I have multi contact points with Slack app on my opensource Grafana system.
Some of them are working and some stopped last week.
I replace the webhook urls and test it seems to be fine with the test but on a real alert there is no notification.

I’m getting this error from Grafana after trying to test the contact point

Failed to send test alert.: failed to send Slack message: failed to send request: Post XXXX unsupported protocol scheme ""

from Grafana logs

Version v10.0.3
Any idea?
Thanks

Did you followed doc properly?

Hi @jangaraj Yes I did.
I follow this doc and I needed to create new slack app and not using old incoming webhooks.
I fixed the issue it was Slack side.
Thank you!
