RPC_NT_INVALID_RPC_PROTSEQ

RPC_NT_INVALID_RPC_PROTSEQ is an NTSTATUS value used by the Windows RPC runtime. This status is about the protocol-sequence identifier supplied to the RPC runtime. The sequence is not accepted as a valid RPC protocol-sequence name, so the runtime cannot use it to interpret the network address, endpoint or binding options that depend on that transport.

It is narrower than RPC_NT_PROTSEQ_NOT_SUPPORTED. A supported-status failure starts with a valid sequence that the host cannot use; this status means the requested sequence is not valid in the first place.

The protocol-sequence identifier is malformed or unknown to RPC

Compare the configured sequence against the documented identifiers used by the target RPC transport, including spelling and case where configuration tooling imposes it.
Validate the sequence together with the endpoint syntax; an endpoint that is meaningful for one transport is not automatically valid for another.
Do not diagnose firewall, DNS or listener state until the protocol sequence has been accepted.
