NVidia repository invalid metadata

In LEAP 15.5, my newly installed NVidia repository is no longer recognized as valid:

# zypper patch
Retrieving repository 'NVIDIA' metadata ...........................................................................[error]
Repository 'NVIDIA' is invalid.
[NVIDIA|https://download.nvidia.com/opensuse/leap/15.5] Valid metadata not found at specified URL
History:
 - [NVIDIA|https://download.nvidia.com/opensuse/leap/15.5] Repository type can't be determined.

When I use Firefox to go to download.nvidia.com, I get:

Index of /

So what you try to access does not exist (any more?).

Are you sure that URL is correct (I am no Nvidia user, thus I do not know if it should be correct or not).

The link is correct, except that the 15.5 directory throws a 404 error.

Strange. zypper just updated all of my NVidia drivers.
How does one fix the repository?

The repo got fixed some minutes ago…
https://download.nvidia.com/opensuse/leap/15.5/

One does not fix it this is a problem the server people must address
