The 1961 Hague Convention works in both directions at once. An apostille is enough only when both countries are party to it. If either side is outside, the document goes through consular legalisation instead — a slower, multi-step and costlier route that is worth knowing about before the deadline, not after.
The check runs against the same apostille data as the rest of the monitor: 78 of the 90 jurisdictions tracked here are parties, 12 are not. Both jurisdiction cards are linked from the result.

At least one of the two is not a party, so the convention does not apply to this pair. The document needs the full chain: notarisation, the issuing state's foreign ministry, then the receiving country's consulate.
What this does not cover
Two things this cannot see. A state may object to another state's accession, and between that specific pair the convention does not operate. And neither route says anything about translation requirements, which are set by the receiving authority.
