The error "Not a valid PEM pre boundary" you're encountering typically indicates an issue with the formatting of SSL/TLS certificates, particularly when a certificate does not have the correct PEM (Privacy Enhanced Mail) headers. This can happen if Dify is trying to establish a secure HTTPS connection and the certificate involved is improperly formatted. A properly formatted PEM certificate should start with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.

To address this issue, ensure that:

• Any SSL/TLS certificates used by Dify or required for communication with external services over HTTPS are correctly formatted.
• Check Dify's configuration for any SSL/TLS certificate settings, ensuring they are correctly implemented.
• If a network proxy or firewall is part of your setup and uses SSL/TLS certificates, verify their configuration as well.

This error might not be directly related to the process of adding a model in Dify but could stem from how Dify is set up to communicate over HTTPS, either internally or with external services. If you can provide more details about the specific context in which this error occurs, it would help in identifying a more precise solution.

I use dify in private net，it don't have domain, so I doesn't use ssl, use http not https

@WhiteRoseinShangHai Try checking the "encrypt_public_key" in table "tenants", it seem you got an invalid value.
