Stardew Valley servers feature an expansive crossplay, allowing players on all platforms to connect and play on a server. This includes mobile iOS or Android players, provided they follow the necessary steps to unlock multiplayer. This allows players on mobile platforms to play; however, mobile users may run into issues with servers with many mods or other extra content installed.
Note: This feature is NOT supported for iOS Arcade, as Arcade policies limit functionality.

Note: If mobile players can't connect, stop and start the server.
