NS_E_CURL_INVALIDPORT: URL parsing and validation
NS_E_CURL_INVALIDPORT (0xC00D132C) means the authority contains a port representation that the URL helper cannot accept.
Evidence to preserve
Record the raw authority, parsed host and port text, including signs, whitespace or non-decimal characters, and the API that parsed it.
Focused verification
Retry with the default port omitted or with a valid explicit port while keeping host and path unchanged. This distinguishes URL syntax from a later connection-refused result.
