same problem.
use code-server -vvv to start it ,then access code-server,you will see some logs.

@WeAreAllLonlyGhost can you post your logs? I'm using 4.0.2 without issue

I tried using 127.0.0.1:8189, but still 404,I don't know if code-server -vvvv works right. I didn't find any useful information in the browser log file (maybe I don't know how to use it), code-server is installed with yam, I remember there is a version of arml7, but it doesn't work on rpi4B

Can you try installing the beta version with yarn global add code-server@beta and trying that?

Can you try upgrading to 4.1.0 to see if the issue is resolved?

It is resolved in 4.1.0. Thanks a lot!!

Hooray!!!! Thanks for confirming. Happy coding!
