Impact

• curl -Iv https://worksheets.codalab.org fails with a certificate verification error
• The cl CLI cannot connect — SSL verification fails on all commands (e.g., cl work main::)
• Users cannot submit to competitions hosted on CodaLab Worksheets (e.g., HotpotQA and others)
• Workarounds like disabling SSL verification (curl -k or --insecure) are not acceptable because authentication credentials are transmitted

Expected: valid TLS handshake
Actual: certificate verification failure (certificate expired Jun 22 2026)

Resolution Required

The server-side TLS certificate for worksheets.codalab.org must be renewed by the CodaLab administrators. No client-side fix is possible.

After renewal, users can verify with:

curl -Iv https://worksheets.codalab.org
cl work main::
