Expired SSL certificate on ops.clemson.cloudlab.us

[Julian W]

Hi,

The SSL certificate for ops.clemson.cloudlab.us has expired as of February 1, 2026. This is blocking access to the web SSH interface (and likely other services on that host), as modern browsers refuse to connect.

Cert details:
- Issuer: Let's Encrypt (R12)
- Expired: 2026-02-01T17:21:28Z
- Error: SEC_ERROR_EXPIRED_CERTIFICATE

Could the cert be renewed when possible? Thanks!

Is it better now?

The problem seems to be specifically with https://ops.clemson.cloudlab.us/webssh, which is used by the IPMI console access. I still get this error when trying to access the console of an arbitrary server on the Clemson cluster. There isn't even an "Continue anways" button, Firefox (or Chrome) both simply refuse to continue.

Should be fixed for real this time.

Yes it works now, thank you!
