I redirected on the page : https://HOST/index.php/unsupported
If a acknowledge with the button "Continue with this unsupported browser" i have a 404 error because the URI is in double. I redirected to https://HOST/index.php/index.php/apps/dashboard/

I'm having difficulty reproducing this.

Does this same environment work fine with a supported browser?

Also, was your installation in/accessible via a subfolder URL by chance (i.e https://domain.com/nextcloud versus https://nextcloud.domain.com)? That can make a difference.

Since you you didn't provide one in your report, I have to ask: is your config modified in any way or - better yet - can you provide it?

=> YES

lso, was your installation in/accessible via a subfolder URL by chance (i.e https://domain.com/nextcloud versus https://nextcloud.domain.com)? That can make a difference.
=> I have 2 Nextcloud installation with same issue.
=> Install number 1 is redirected to https://domain.fr/nextcloud/index.php/nextcloud/index.php/apps/dashboard/ (because nextcloud access from subfolder
=> Install number 2 is redirected to https://domain.fr/index.php/index.php/apps/dashboard/
=> So with subfolder or root install it's the same.

is your config modified in any way or - better yet - can you provide it?
=> Default configuration. But one upgrade from an 23 install and the other is upgrades from a lot of years, first install was Owncloud 6. But all upgrade are only Major to Major+1.
