Prefect Community

Hello everyone!! I’m trying to register a flow from my Gitlab server as a part of a CI/CD pipeline…but I’m always getting this error: `requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=4200): Max retries exceeded with url: /graphql (Caused by NewConnectionError('&lt;urllib3.connection.HTTPConnection object at 0x7f373f0b32b0&gt;: Failed to establish a new connection: [Errno 111] Connection refused'))`

I have installed prefect in a virtual enviroment during pipeline execution and also set up ./prefect/config.toml with [servers] host=“ip_to_host” but I only see localhost  in the error. Also the EC2 instances have all necessary ports opened and prefect is set up as backend server

I’m really stuck on this and maybe I need another pair of eyes…THX

I forgot to say that the gitlab runners are docker executers….one is directly running in the host and another one is a docker container but with network = host as I’m trying to debug this problem

Hey <@U022WPJ1JNR>, hard to pinpoint what’s going on but you are right that the `localhost` does seem to be the issue. I guess we need to test if that `config.toml` is being picked up? Not sure how to test right now, will ask the team.

<@U022WPJ1JNR> it looks like you have `servers` as your config.toml section header, which should be `server` , try adjusting that

<@UN6FTLFAS> going to check that out…hope that silly thing is the issue…

If that doesn't work I'd also check that you're creating `.prefect/config.toml` in the correct location; I believe it needs to be in the home directory (`~`)

nope, it doesn’t work…in the pipeline I have [server] …. I’m going to check the home thing. thanks

Now works…thanks <@UN6FTLFAS>, it works with ~/.prefect Sometimes you didn’t see the silly things by yourself :slightly_smiling_face:

Ah perfect, glad you got it sorted! :smile:
