No Apps Button?

I installed Nextcloud 24.02 from source.
Almost function works well.
But there is no apps button as logined.
Is there need to set for apps button on config.php?


Are you the admin user?
Can you access https://cloud.server.tld/settings/apps
Post errors. Do you use an adblocker? Can you test with another browser and another computer?

No. All admins can see “Apps”.

I can’t access to https://cloud.server.tld/settings/apps with chrome, firefox.
Can’t not find server.

You have set your servername in the url? Post screenshots of your error. You can black some parts.

No servername in config.php.

Your server has got an url e.g.
Open this path (for your domain/server):
(substitute with your server url)
Post errors.

has error

Not Found

The requested URL was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Sorry. Please test this with your domain:

I think this is your error no access (sorry german):

Zugriff verboten
Der angemeldete Benutzer muss ein Administrator sein

But result is

“File not found.”

I reinstall nextcloud everything even database.
