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 @[email protected]: https://lemmy.ml/comment/948928

    Are you running lemmy 0.18.0? It breaks a bunch of internal network connectivity. The short term solution is to add an external network to both the lemmy-ui and pictrs containers, then you can change http://pictrs:8080 to http://your_domain.

    Note: there are also some issues in 0.18.0 with comment federation at the moment. Please reply to confirm this comment was seen, thanks!

      Well, butter my butt and call me a biscuit. In implementing this, I stumbled upon an issue: I had the url in pictrs_config, when it should have been pictrs.

      Now at least the logs are showing an error that matches the toaster: ``` 2023-06-25T13:09:27.753749368Z 2023-06-25T13:09:27.753609Z WARN lemmy_server::root_span_builder: error decoding response body: expected value at line 1 column 1 2023-06-25T13:09:27.753809022Z reqwest::Error { kind: Decode, source: Error(“expected value”, line: 1, column: 1) }

      
I already have those containers in an external network, and changing the URL hasn't fixed it.

        Oh, this span builder error. Yeah I’ve been seeing that error since I upgraded to 0.18.0. Sorry, I don’t have a solution for this one.

        Glad you figured out your pictrs error though! One other thing I did was update my resolve.conf so that valid DNS hosts were making it to the containers. Also try rebooting your host.

        Feel free to add to this discussion. https://github.com/LemmyNet/lemmy/issues/3314

          Yeah no, DNS works in the containers:

          dot@deepthought:~# docker exec -it lemmy-lemmy-1 ping pictrs
PING pictrs (192.168.7.2): 56 data bytes
64 bytes from 192.168.7.2: seq=0 ttl=64 time=0.079 ms

          However, your hunch did actually turn out to be correct in that there’s still a networking issue: I opened a port for pictrs and hit the API with postman, and noticed it would show up in the pictrs logs which were empty before. So I changed the url to the host’s IP and the open port, and now it works. :)

          lemmy.hjson:

            pictrs: {
    url: "http://192.168.123.21:4808"
    api_key: "apikey"
  }

          docker-compose.yaml:

          pictrs:
...
  ports:
        - "4808:8080"

            Oh, good idea! Whatever works for you. I spent several hours yesterday trying all sorts of networking hacks to resolve the issue on my instance. I eventually found a combination that worked for me.

            The concern here is we are all solving this issue in slightly different ways on our self hosted instances. Eventually, I hope the lemmy dev team releases 0.18.1 fixing all these issues for good.

    Did you run the chown -R command for the volume bind? Is the pictrs actually up and running? Check docker ps | grep pictrs and see if it is actually running. Also check the logs to see if there are any errors.

        Hm… What else… Did you modify the docker-compose.yml by chance? Are lemmy and pictrs sharing the same network? Other than that I’d be at a loss.
