Are there any logs in the browser you can share?

[adeleporte]

I have the same issue (also with some other extensions) when code-server is exposed externally (http, https, w/ or w/o password). However, it works when using 127.0.0.1 (with SSH tunnel for example).

Seems to be related to sha-256 calculations...
I have this error message in the browser logs : ERR Can't compute sha-256: t@http://10.*.*.*:8081/static/out/vs/workbench/workbench.web.main.js:798:15149

[jsjoeio]

Interesting 🤔

Running locally on localhost:8080, I can't reproduce.

I tested it by exposing via ngrok and it works as expected as well:

If you could paste a screenshot or the entire browser logs, that would help.

[adeleporte]

Sure:

Very helpful! Looks like your error is originating here:

https://github.com/microsoft/vscode/blob/main/src/vs/workbench/browser/webview.ts#L11

Can you try using something like ngrok and seeing if you still get the error?

If you do get the error, not related to HTTPS
If you don't, probably related toHTTPS

[adeleporte]

Thanks for the update. Unfortunately, I can't use ngrok (company policy).

But there is a very simple way to reproduce it, by using the docker image:

docker run -d -p 0.0.0.0:8080:8080 --rm codercom/code-server

If I access to http://127.0.0.1:8080, or http://localhost:8080, everything is working fine.
If I access to the docker host directly, let's say http://172.20.5.109:8080, the extension is broken.

This docker image doesn't use https, so I would say that the issue is not related to https.

Thanks for looking at this issue!

[jsjoeio]

If I access to the docker host directly, let's say http://172.20.5.109:8080/, the extension is broken.

That means you're not using HTTPS so service workers won't work so the extension shouldn't work. I think that proves that this is related to HTTPS then. And I don't think there's any way to work around this unfortunately.

[adeleporte]

Hum interesting..

I have created a new "https" docker image with this Docker file:

FROM codercom/code-server:latest
COPY config.yaml /home/coder/.config/code-server/config.yaml
ENTRYPOINT ["/usr/bin/entrypoint.sh", "."]

and this config file :

bind-addr: 0.0.0.0:443
auth: password
password: test
cert: true

docker run -d -p 0.0.0.0:443:443 --rm adeleporte/httpscoder

And this time, it does work with any address/fqdn...

I will re-check with my previous configuration.
Thanks!

[jsjoeio]

Well that is certainly good news to my Monday! Sounds good!

[code-asher]

Closing since it seems this is solved?
