hello FireDex, what is the error code (under technical details) when you try to access the site?

It says mozilla_pkix_error_ca_cert_used_as_end_entity

thanks, mozilla's documentation for developers contains the following information for this error code:

What it means? A certificate with a basic constraints extension with cA:TRUE is being used as an end-entity certificate

What can I do? Re-generate the end-entity certificate without the basic constraints extension _{https://developer.mozilla.org/en-US/docs/Mozilla/Security/x509_Certificates#Error_Codes_in_Firefox_2}
