Hi,

In the last 4 hours the server is going down returning

Either:

2023-04-20T20:44:59.386 proxy[7b84784b] fra [error] could not make HTTP request to instance: connection error: Connection reset by peer (os error 104)

Or

Failed to proxy HTTP request (error: no known healthy instances found for route tcp/443. (hint: is your app shutdown? is there an ongoing deployment with a volume or using the ‘immediate’ strategy? if not, this could be a delayed state issue)). Retrying in 20 ms (attempt 1)

The application running on truckopedia.ro domain

What is the name of your application? Can you check fly logs?

I can access https://truckopedia.ro/ from my end (Seattle, USA).

The app was down and up in the last hours without anyone to touch anything in the environment

“Connection reset by peer” means the application process is dropping the connection before it responds. Usually this happens because an app stops accepting connections or requests. You’ll most often see health check failures.

You can troubleshoot this with a few tools.

First, see if health checks are passing, either with fly checks list or here: Health check history on Monitoring Page

It might also happen if an app is in a crash loop. If you run fly status --all and fly vm status <id> you can sometimes see what’s up.

All pass without any issues. Decided to restart maybe it had a glitch due to earlier incident that was reported in the dashboard
