Lemmy Support

So I'm currently trying to set up an instance, and I'm unable to upload pictures. The following toaster appears: https://imgur.com/d0MUhUb

And in the logs I see this:

2023-06-25T10:48:11.127198782Z 2023-06-25T10:48:11.127080Z  WARN lemmy_server::root_span_builder: Request error: error sending request for url (http://localhost:8080/image): error trying to connect: tcp connect error: Address not available (os error 99)
2023-06-25T10:48:11.127262799Z Reqwest(reqwest::Error { kind: Request, url: Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("localhost")), port: Some(8080), path: "/image", query: None, fragment: None }, source: hyper::Error(Connect, ConnectError("tcp connect error", Os { code: 99, kind: AddrNotAvailable, message: "Address not available" })) })

I have a pictrs container up, and set the following options in lemmy.hjson:

  pictrs_config: {
    url: "http://pictrs:8080"
    api_key: "apikey"
  }

Also tried it with pictrs_url: "http://pictrs:8080" (as described here), but that didn't help either. Why is lemmy trying to access localhost:8080 rather than pictrs:8080?

Edit: This has been resolved, thanks to @slashzero@hackbox.social: https://lemmy.ml/comment/948928
