Now there's another issue, bors is not responding to comments.
If I do bors ping nothing happens.
Whereas if I visit app_name.herokuapp.com/health it returns healthy!
Not sure what's the issue now. I do have staging and trying branches on my repo.
Thanks once again 
.
Is there a way to debug whether bors is receiving commands?
Sure. In the Developer section on GitHub, where you got the Client Secret, there’s an Advanced tab. You can see all of the webhooks that get sent to your app in there.
Sorry I meant whether bors is receiving the commands or not!
I can see that Github is indeed sending requests to bors.
Because I have the CI setup on my private repo and bors ping doesn't respond!
bors ping should be the way you check if bors is receiving the commands.
A good way to check if it's correctly associating with your site is to log into the bors dashboard. Does it show your repository in the Repositories list?
Yes. I am able to see the repositories in the repositories list. Plus I am able to see the Pull Requests as well.
When you send a command to bors, and you can see the command being sent as a webhook, is bors responding with a 200 OK, or a 500?
Also, in the Heroku dashboard, can you see the incoming webhook requests?
I checked using heroku logs --tail --app <app_name>, it seems the bot isn't receiving any webhooks!
According to the “Response (200)” tab in that Advanced page on GitHub, what exactly did bors send in response to the webhook?
This is all it sent, which doesn't look right to me, cause there isn't any body associated with the response!?

I can see that bot does get a webhook. Logs:

The issue here is that it only gets a webhook if I manually redeliver the payload from the Advanced settings. If I do bors ping it does not get the webhook, which is really wired!
Additionally bors gets webhooks, if I remove or add a repository. So it never gets a ping when I comment on a PR. I have double checked the PR permissions thought and it's set to Read&Write.
Now there is this log:
2021-09-08T01:45:54.431365+00:00 heroku[router]: at=info method=GET path="/socket/websocket?token=SFMyNTY.g2gDYQFuBgAgmhDDewFiAAFRgA.DzcQr6lokwUxgp2R3QNOQstySdYc2LL8YkSyr5pRYTs&vsn=2.0.0" host=borsts.herokuapp.com request_id=025184dd-9a1b-4c68-b286-cd2d1e14520b fwd="213.238.192.194" dyno=web.1 connect=0ms service=303985ms status=101 bytes=226 protocol=https
Not that this took around 5 minutes, which is exactly when I posted bors ping on the pr!!
But there is no webhook log in the Advanced tab for this, so not sure what's going on.
The socket isn’t relevant for what we’re trying to diagnose.
Is it set to receive issue comments on the “Subscribe to Events” section of the “Permissions and Events” page?

OMG, that was the issue. It works like a charm.
Thanks for all the help Michael
