No access to Packages (localhost)

oscon

I am using the latest Automad version with installed local XAMPP 7.4.26 / PHP 7.4.26 behind an http / https proxy for internet access.
Automad works so far, but switching to the individual areas (Dashboard, System settings) is extremely slow!
When accessing Packages, the error message "Packagist packages could not be loaded" (german: Pakete von Packagist konnte nicht geladen werden) appears after a while.
I discovered the problem in other discussions here and assume that it concerns access via cURL behind an internet proxy.
The query via XAMPP Shell and curl confirms my assumption: Access to packages.automad.org is suppressed.
(curl: (7) Failed to connen to packages.automad.orgport 443: Timed out)
In the other discussions, (local) SSL certificates are mentioned again and again:
But is there also the option of configuring an existing proxy (with authentication) for access from Automad to the Packages?

oscon Hi there, I just also commented on the open issue. However, there was another post here in the forum with the same problem that was resolved after updating the SSL certificates.
