Why have my notifications been switched off?
If a notification channel keeps failing to deliver for more than a day, we automatically disable it.
"Failing" means things like:
- Email bouncing
- A Slack webhook URL returning 404
- A Telegram bot being removed from the group
- An expired API token on Opsgenie or PagerDuty
- A webhook endpoint responding with a 5xx for every attempt
We keep retrying for 24 hours. If it's still broken after that, we turn the channel off so you don't end up with stacks of failing retries in the background. You'll see a notice in the app telling you the channel was disabled and why.
How to re-enable a disabled channel
- Head to your monitor's (or team's) Notifications settings
- Find the disabled channel
- Update the broken credentials, URL, or configuration
- Re-select the events you want to receive alerts for
- Save, and send a test notification to confirm the channel works
Once a test notification goes through cleanly, the channel is back in normal operation.
If you're not sure why a channel failed, contact support with the channel type and when it stopped working. We can look up the specific error we received.
