Yum update, Curl error (58): Problem with SSL cert

Registering a off-prem host to a on-prem disconnected satellite. Registration went through. Had one error with IP address subnet mismatch which I resolved. but running yum update shows the below.

Yum update on the host says:

Errors during downloading metadata for repository'xxxx'
- Curl error (58): Problem with local SSL certificate for https://the-disconnected-sat.xxx/.../..../...repomd.xml [could not load the PEM client certificate, OpenSSL error:02001002:system library:fopen:No such file or directory, (no key found, wrong pass phrase, or wrong file format?}]
Error: Failed to download metadata for repo 'xxx': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors tried.

Any ideas?
