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
