Hi community. I'm trying to get Prefect server (v0.12.5) working locally but GraphQL can't connect to Postgres. There are a couple of other questions in this channel that describe a similar issue, but both relate to config.toml. I haven't written config.toml and I haven't set any

PREFECT__

environment variables, so I'm using defaults.

When I run

prefect backend server && prefect server start

the images are pulled and containers set up. The logs indicate that GraphQL (

hasura_1

) cant' connect to Postgres. However, later, Apollo (

apollo_1

) is able to build the schema and start the server.

In the UI, I see...

Would you suggest writing config.toml? Is this a Docker networking issue? I'd appreciate any pointers. Thanks!

Well, that's strange. I've just checked the UI in Chrome and everything's fine; not in Firefox (78.0.2), however. So, neither a configuration nor a Docker issue, apparently.

Ah that’s weird, so just to clarify, it is working for you in Chrome but not Firefox?

That's correct, yes. So, the underlying components are all working correctly: the UI, Postgres, Apollo, etc. But FF isn't connecting to GraphQL but Chrome is.

Interesting! It appears to be working for me in Firefox (Mac OSX Catalina)

Lucky you! 🙂 For me, FF's network tab is displaying 200s for the requests to the GraphQL endpoint but "Attempting to connect..." in the API Status.

Would you open an issue on the repo with some information about this and your system?
