NS_E_CURL_INVALIDHOSTNAME: URL parsing and validation
NS_E_CURL_INVALIDHOSTNAME (0xC00D1326) means the URL authority contains a host representation rejected by the parser.
Evidence to preserve
Record the raw authority, parsed host, brackets if an IPv6 literal is used, port separator and any percent or internationalized-name representation.
Focused verification
Replace only the host with a known-valid host while retaining scheme, port and path. If parsing advances, focus on host syntax rather than connectivity or DNS reachability.
