You didn't say what error it gives.

The difficult we do right away... ...the impossible takes slightly longer.

when do connect error in this line

conStatus.Text = "Connected to: " + client.RemoteEndPoint.ToString();

[Richard Andrew x64]

Yeah, what is the error message?

The difficult we do right away... ...the impossible takes slightly longer.

[heba abu ghaleih22]

Cross-thread operation not valid: Control 'conStatus' accessed from a thread other than the thread it was created on.

[Richard Andrew x64]

This gives the solution: Cross Thread Calls[^]
