Having great difficulty tracking down what is causing the below error when attempting to update any package from any repo. I have tested multiple repos by setting all others to disabled. I have cleaned all cache and removed any dnf yum cache files.
# dnf -v update
Loaded plugins: builddep, changelog, config-manager, copr, debug, debuginfo-install, download, generate_completion_cache, needs-restarting, playground, repoclosure, repodiff, repograph, repomanage, reposync
DNF version: 4.2.7
cachedir: /var/cache/dnf
repo: downloading from remote: AppStream

Each time I attempt a dnf update, load average on the server goes thru the roof, up to 40x
curl can access the mirror site.

I have also tried using baserurl in .repo, same error
I have also replaced the baseurl with one of the url's returned by curl, same error
I have tried many suggestions such as yum/dnf error: Failed to download metadata for repo and similar, none work for me. Some articles point to bugs in the env vars for $releaseserver etc. I have also tried replacing with actual values. same error.
Internet connection obviously OK due to curl result. No proxy used. DNS OK
cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)

Any suggestions would be greatly appreciated.
