YUM ERROR: Failed to retrieve group file for repository: rhel-x86_64-server-7

A week ago, a yum update on all my Rehdat 7 servers, outputs the following error: **Error:** Failed to retrieve group file for repository: rhel-x86_64-server-7 I tried doing a yum clean all, but that did not work. I suspect it's a problem with the the satellite redhat software server that we use here. I registered a totally new node with that server, but the same error occurs. A yum check-update after clean all with debugging on shows it tries to download the file but fails. But downloads all the other files.
