Error: Failed to download metadata for repo 'cloudlinux-x86_64-server-8': Cannot download repomd.xml: 
Cannot download repodata/repomd.xml: All mirrors were tried Often errors like this can be resolved by running `dnf makecache` 

Environment

• CloudLinux

Solution

1. Try re-registering the server by following instructions from the article:  How to Register CloudLinux OS with Key-based/IP-based Licenses?
   
   
2. Clean yum cache:
   

   # yum clean all
   # yum makecache

If that doesn't correct the issue, make sure that port "443" is open and that the "stat-api.cloudlinux.com" server can be reached:

# curl https://stat-api.cloudlinux.com/
curl: (7) Failed to connect to stat-api.cloudlinux.com port 443: Connection refused

After opening the port (expected behavior):

# curl https://stat-api.cloudlinux.com/ && echo
404: Not Found
