30117: Certificate cannot be parsed

Twilio returns this error when it can't parse the certificate you uploaded for a Link Shortening domain. Upload the certificate in PEM format and make sure the certificate content uses the expected PEM block structure.

• The uploaded certificate data is corrupted, incomplete, or missing required content.
• The certificate is not in PEM format.
• The certificate does not start with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.
• The uploaded certificate includes extra newline characters at the beginning or end.
• If you use the API, the TlsCert value is not formatted correctly for the certificate upload request.

• Re-export or regenerate the certificate in PEM format, then upload it again.
• Confirm the certificate begins with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE-----.
• Remove any extra newline characters before the first line or after the last line of the certificate.
• If you upload the certificate through the API, send the TlsCert parameter in the required format. Include the concatenated certificate and private key value exactly as shown in the Link Shortening onboarding flow.
• If the upload still fails, generate a new certificate and private key pair and verify that the private key is also in the expected PEM format before retrying.
