Webhook: "Could not connect to server"

I have tied 2 different webhook endpoints. Requestbin, which I verified works by running their example curl script on my Linux server and webhook.site.

On both occasions, once I create the webhook in Orchestrator, and paste in the URL generated by the endpoints listed above, itr simply reads “Could not connect to server” underneath.

There seems to be no other information to troubleshoot this. I’m at a loss - its should…just work.

Additional info, FWIW, Ochestrator is hosted by a reseller (i.e., we are a tenant account)

Hello Scott,
In the First video, you will see how Use Orchestrator Webhooks in Power Automate:

In the second video you can see how I use the Slack Webhooks to communicate with UiPath:
