Failed to download metadata for repo 'CyberPanel'

Running on CentOS 8, just tried to run yum update and got the following issue, anybody else experienced this or have a fix for it.

We have several servers running CO 8 with CyberPanel and most are absolutely fine, but have this issue on two of them suddenly…
