code-server v4 unable to load resources (e.g. new theme) -- requesting to port 80?

[drmrbrewer]

I'm getting the following error in the console when trying to load a new theme (in a fresh v4 installation):

  GET https://code-server.mydomain.com:80/vscode-remote-resource?path=%2Fusr%2Flib%2Fcode-server%2Fvendor%2Fmodules%2Fcode-oss-dev%2Fextensions%2Ftheme-defaults%2Fthemes%2Fdark_plus.json&tkn=0000 net::ERR_SSL_PROTOCOL_ERROR

  ERR Unable to load vscode-remote://code-server.mydomain.com:80/usr/lib/code-server/vendor/modules/code-oss-dev/extensions/theme-defaults/themes/dark_plus.json: Failed to fetch: Error: Unable to load vscode-remote://code-server.mydomain.com:80/usr/lib/code-server/vendor/modules/code-oss-dev/extensions/theme-defaults/themes/dark_plus.json: Failed to fetch

	at async Z.restoreColorTheme (https://code-server.mydomain.com/static/out/vs/workbench/workbench.web.api.js:1926:79687)

My installation is in this context: #4529 (comment) (just replacing curl install.sh | sh with curl install.sh | sh -s -- --version=4.0.0).

I also have the following ENTRYPOINT (i.e. binding to 8443 rather than 8080):

ENTRYPOINT [ "code-server", "/root/workspace", "--bind-addr", "0.0.0.0:8443" ]

It all seems to fire up just fine with v4... just not able to change theme for a start.

I'm also seeing the following (not really doing anything to prompt it):

I suspect that this is a duplicate of: #4607 and also #4604

When I access code-server via http rather than https, switching theme does work... though the theme previews are not shown so it's a case of choosing the theme via "Browse Color Themes".

@jsjoeio @code-asher I've set up a demo deployment of code-server v4 over here so that you can play around with it. Password is issue-4608.

Thank you for the bug report and the demo! Will try to fix this asap.

This is the Dockerfile used to build the code-server image (it's basically what @code-asher suggested here but with a few extra bits and pieces):
