Socket Connection doesn't work on WatchOS 9

I noticed that socket connections doesn't work on real devices on watchOS 9.

It was working well on WatchOS 8 & WatchOS 7.

Is this a bug or a new restriction for WatchOS 9 ?

Similar issues:

• Cannot connect to server on watchOS 9
• WebSocket connect failed in WatchOS9
• Database socket calls do not work on watchOS 9
