STATUS_STRONG_CRYPTO_NOT_SUPPORTED
Security negotiation required stronger crypto than this host supports
This status belongs to security negotiation. The remote side requires a stronger cryptographic mode or algorithm set than the local machine can use in that context.
Identify which strong-crypto requirement the proposal requested and which provider or peer rejected it. Check cipher and key-exchange capabilities before weakening policy or changing unrelated firewall rules.
What to inspect
- Compare local and peer crypto policy.
- Check OS version, FIPS policy, certificate algorithms, and IPsec proposal lists.
- Do not treat this as a password failure.
