How do I refer a local webpage?

I recognized, while Home Assistant promotes a weather radar page on the webpage card, the page does not reload. So I followed advise in the forum and created a local page in File Explorer “/config/webpage/weather.html” that I tried to link as /local/webpage/weather.html - but it’s not found. It shows a white page in the panel, but one I right-click “view frame souce”:
. . No webpage was found for the web address:
. . ###://192.168.68.200:8123/local/webpage/weather.html
. . HTTP ERROR 404
When I enter like /local/webpage/ I see a sad face, not a white page.
(###=http > An error occurred: Sorry, new users can only put 2 links in a post.)

I checked in Terminal:
. . ➜ ~ cd /config/webpage
. . ➜ webpage ls -la
. . total 12
. . drwxr-xr-x 2 root root 4096 Oct 4 10:32 .
. . drwxr-xr-x 13 root root 4096 Oct 4 10:31 …
. . -rw-r–r-- 1 root root 363 Oct 4 10:26 weather.html

Any ideas or hints?

The root directory of the HA webpage for local pages is /config/www

That is where you should store pages you want to use.
