Grav installation on 1&1 IONOS

EDIT: I just discovered that this error is appeared too when trying in local with apache2, but with XAMPP on Windows It's working....

Hello!
I just tried to add Grav to my host (transfert the zip file with FTP and then unzip it with SSH), but it's not seems to be working.
I extracted grav-admin in the root folder, and when I access my website with

https://mywebsite.com/grav-admin

it redirect me to

https://mywebsite.com/grav-admin/admin and then

Error 404

I tried to edit .htaccess by uncommenting RewriteBase / but not working either..

Am I doing something wrong?
Thanks for any answers!

Hello admin6900,
I have a similar problem uploading the website on IONOS. But I see a white (blank) page. Have you found a solution in the meantime? Thanks für an answer!

@admin6900, You probably have fixed the issue in the mean time, but the issue resembles a previously posted issue. It had to do with the configuration of Apache's virtual host.

It needed the following in the virtual host definition:

AllowOverride All
Require all granted

@Manu, Since you are not getting a 404 error, I'm not sure if your issue is the same.
