Individual favicon only used when logged in

[FalconMuc]

Hi,

I defined an individual favicon in a „static“ subfolder called „branding“ as described, changed the „branding“ section in sftpgo.conf and restarted sftpgo.

I‘m using an Iphone at the moment to login. After I logged in as admin, I can immediately see the favicon in the browser tabs. Everythings looks fine.

But when I logout and stay at the admin login screen I see the yellow standard favicon in the browser tabs of my Iphone.

I already cleared the cache and rechecked everything:

Logged in: New favicon
Logged out: Old standard favicon

What am I doing wrong?

Thank you
Thomas
