I see a similar issue already described here . I have a 30seconds timeout on each call of /settings/admin/overview and I do not get proper update notifications. I'm on NGINX on Arch. Happens since NC 22b3, now unsure if related to NC server code, or if it is a webserver configuration error. Anyway, the issue seems related to calling www.nextcloud.com as http instead of https :

The server does not see new updates. But if forcibly click "Open update window", it successfully installed Nextcloud 22.0.0 RC1.

After the update, the old problem remained:
"Could not connect to the App Store or no updates have been returned at all. Search manually for updates or make sure your server has access to the internet and can connect to the App Store."

And in the magazine there is still the same error.

In parallel, there is another Nextcloud 21.0.2 server, with the same Nginx + PHP 7.4 configuration. And there is no such problem.

Having the same issue, started with beta 1 and still here in RC1.
The issue is related to the changes in /lib/private/Http.
If I take the Http lib from Nextcloud 21.0.2 and place it in Nextcloud 22 the issue goes away.

I followed what you said on #27582 (comment) and I can confirm that my Nextcloud's updates and notifications now work again as expected. Thanks buddy!

Hoping this gets resolved.
