CentOS - Feb 2022 - CentOS Stream 8 dnf fails

Every time I run dnf, I get this:

========[root at vmhost2 ~]# dnf upgrade 
CentOS Linux 8 - AppStream                                                      
70  B/s |  38  B     00:00
Error: Failed to download metadata for repo 'appstream': Cannot prepare
internal mirrorlist: No URLs in mirrorlist
========
I tried disabling the repository, but that only gives me exactly the same error
for the baseos repository.  I doubt it is a problem in the .repo files. 
Something else is going on.

Ping to mirrorlist.centos.org works on both ipv4 and ipv6, so I know that both
name resolution and network connectivity are working.

Thanks!

That's because you are still on CentOS 8 not 8-stream.  The C8
repositories are now empty. (The equivalent repo for 8-stream is
labelled "CentOS Stream 8 - AppStream".)

To move to 8 Stream, see https://centos.org/download/

You will also probably soon get some recommendations to not move to 8
stream and to use one of the other clone distros ...
