[Bug]: Can't enable or disable apps after upgrade to v30.0.0

[kaffeeringe]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).

• I agree to follow Nextcloud's Code of Conduct.

Bug description

See #44685 - I can't enable apps because of this CSP error. It worked before the update.

Steps to reproduce

1. I click "enable"
2. It says "This app cannot be enabled because it makes the server unstable"
3. Browser console tells me "Content-Security-Policy: Die Einstellungen der Seite haben das Laden einer Ressource (connect-src) auf http://example.com/apps/files/ blockiert, da sie gegen folgende Direktive verstößt: "connect-src 'self' blob: https://stun.nextcloud.com:443""

Die Einstellungen der Seite haben das Laden einer Ressource (connect-src) auf http://example.com/apps/files/ blockiert, da sie gegen folgende Direktive verstößt: "connect-src 'self' blob: https://stun.nextcloud.com:443""

Are you, in fact, using http?

You didn't really give us much to go on since you left the Issue template basically blank.

This CSP error suggests a misconfiguration, generally speaking.

Check your browser inspect Network tab while recreating the problem. Make sure reasonable URLs are appearing, no mixing of http and https, etc.

@joshtrichards

here is my capture.
this image shows this site is running under https scheme
but when i try enabling an app, the request is blocked due to mixed scheme.

Same issue here. Worked fine before the upgrade. After upgrade apps are no longer manageable.

My Instance runs under plain http behind a reverse proxy which handles TLS.

This CSP error suggests a misconfiguration, generally speaking.

Why is it suddenly misconfigured after an upgrade when everything was working fine before? Do we need to migrate our configuration to some new format introduced in 30? How?

[joshtrichards]

Why is it suddenly misconfigured after an upgrade when everything was working fine before?

No idea because not one person reporting this in this issue has provided basics like their configuration. ;-)

[joshtrichards]

Under Network in the browser inspect, check the request[s] to https://cloud.domain.tld/apps/files[/] and post the request+response headers.

[kerus1024]

here my some configuration.

forceing https (on config.php) doesn't change anything, behavior is same. only enable or disable apps on administration

browser info on devtools network tab:
server responses redirecting to http even though on https scheme server
