Hey there! We've found the following might help you get unblocked faster:

• 🧵 Healthcheck failed

• 🧵 Healthcheck "service unavailable" but endpoint works when deployed

• 🧵 port binding of a public docker image service

If you find the answer from one of these, please let us know by solving the thread!

Apologies but this looks like an issue with the application level code. Due to volume, we can only answer platform level issues.

I've made this thread public so that the community might be able to help with you query.

Is the application even running ?
Did you specify a run script in the start command ?

I found solution.
Well, it's a ladder of constant self-disappointment.
First is I disable/skip health check in .toml file and voila, it deploys successfully.

But upon checking, I can't visit the site. Thus, health check fails from the start
Turns out it's a problem with next start and start and standalone serverless stuff.

I mixed up my outdated knowledge with them and contradicted containerization.

It's all good now but thank you guys.
