Ran the Libre Weather app for the 1st time. I simply get:
Error loading page
Domain: undefined
Error Code: -1
Description: net::ERR_SSL_UNRECOGNIZED_NAME_ALERT
The app is rightfully named because you can tap a gear and choose a server other than the default https://weather.pd-dev.xyz/ service. But this server seems to be the only public server, so I cannot try another – unless I am ambitious enough to self-host a weather server (which is not really feasible for me ATM).
I get the same error when visiting the server with a normal browser. Hence why this is posted to !bugs_in_services@sopuli.xyz.

Oof! Good find. That apparently renders the app toast for all but self-hosters. I wonder if it has been down since 2023:
