v1 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v2

I’ve checked the previous related issues and nothing seems to work. Thanks to another related issue I have discovered that the connection to port 8080 in the vm is being refused and with the related issues the cause was a typo but in my case there is no typo as I did not write the fly.tomi contents manually

This was the output of the command vm status

This below is my Dockerfile

As you can see below I tried exposing the port 8080 but didn’t seem to work.

How do I solve the connection refused issue???

Do you know which port your service is listening on? Once you find that out, you can change the port in fly.toml to match it.

Can please tell me how to find out which port is being used or listening to?
This is my first time deploying using Fly.io

This is a dot net thing. It probably has a default port it listens on. Do you see any messages in logs when it boots that say "listening on localhost:5000" or similar?

When I run the application inside the docker the port used is localhost:49153

***v4 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v5

Could this be the port the thing is waiting for or one open for us to use instead of the 8080 set inside the fly.toml Under:
[[services]]

Thank you very much Kurt.

I’ve been reading that same thing for 2 days now and for some weird reason I’ve been overlooking it. My eyes only paid attention to the long gibrish V6 address and its port and ignored that one.
I switched the port under [[services]] inside the fly.toml from 8080 to 80 which the dot net thing is listening on and it deployed successfully now.

It’s great to discuss problems with other people. Being a loner sometimes is not fresh :joy::rofl:. Yeah… now I’m going sleep good 2night​:joy::rofl::joy::rofl::joy::rofl::joy::rofl::joy::rofl:

Oh yes! the [::]:80 makes that really non obvious. I’m glad you figured it out!

Do you know why that [::] is there or would it help if we explained it?
