(Chrome) DevTools failed to load source map: Wrong URL?

I freshly installed an XWiki 14.0 using the docker image behind an nginx proxy (with ssl termination).

When I access the Home page with Chrome I see a lot of warnings in the Console with the following message:

DevTools failed to load source map: Could not load content for https://xwiki.mydomain.de:80/bin/jsx/Panels/Applications?sourceMap=true&minify=false&language=en&docVersion=1.1: Connection error: net::ERR_SSL_PROTOCOL_ERROR

Though it mentions “DevTools”: Might these warnings cause problems with the macros and applications?

Actually, I’m worried that there is :80 in the URL whereas I set in the xwiki.cfg that the URL should be

xwiki.home=https://xwiki.mydomain.de:443/
xwiki.url.protocol=https

I dont see where this port 80 is coming from.

Indeed I can access the files when I remove the :80 from the url.

The missing source maps should not have any affect on the end user. They are only useful when debugging the JavaScript code. Still, would be good to know why the URL is wrong, in case this affects other HTTP requests that you haven’t noticed yet.

Thanks for the response! Do you have an idea, where the :80 is coming from? Do I possibly need to have a look into the default URL Builder sources (which might have a bug)? I think there was a default mentioned in the cfg.
