Unable to send messages on specific iOS device

[tobimori]

I just found this package yesterday and migrated everything from react-native-udp to this. It works great so far! Thank you for this wonderful contribution to the ecosystem.

However, I'm running into the following issue:

One of my devices (iOS) is unable to send messages to any address, be it a multicast address like 192.168.0.255 or a unicast address. It can receive messages from other devices (iPadOS & Android) perfectly fine.

Things I've tried:

• Changing ports
• Restarting the device
• Trying a different message payload
• Trying different IPs (multicast/unicast)
• Using setBroadcast(true)

The app is using Expo SDK 51 and RN 0.75. Both iOS/iPadOS devices are on 17.5.1.

Any idea what this could be? Using the old package, tradle/react-native-udp works on this particular device. (but has other issues)
