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

Questions / Help

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.

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app

FROM base AS final
WORKDIR /app

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.

4

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

5

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?

6

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

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?

The fix for me was to add a PORT as environment variable in Fly.

In the terminal that was:

flyctl secrets set PORT=8080 --app insert-your-app-name-here
