The Windows release has online co-op, but controller support is not a console edition and no cross-platform console pool is officially listed.

Yes—How to Fish supports multiplayer, co-op, and online co-op in its Windows Steam release. The current official store data does not list local split-screen, a specific maximum party size, or crossplay with consoles.

Do not use the full-controller-support badge as evidence of PlayStation or Xbox multiplayer. It means a gamepad can be used with the PC build. The platform page currently finds no official console or mobile release, so there is no announced console matchmaking pool to test.
Before diagnosing a failed invite, confirm both players are on the current Steam build, online in Steam, and using the game's online co-op entry point. Avoid deleting saves or network settings when the underlying issue may be version mismatch or Steam presence. The official sources checked here do not publish a universal port-forwarding requirement.
