[Resolved] Can't upload pictures (lemmy.ftp.rip)

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

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.

One other thing I did was update my resolve.conf so that valid DNS IPs were making it to the containers. Otherwise the containers might not have valid DNS. Also try rebooting your host.

Here is what I did to fix the container DNS lookups failing:

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!

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.
