Analysis by screenshot is always tricky, much better to share the capture.
Looks like the capture was taken at the server and the server respopnds to the income connection attempt SYN with a SYN, ACK, but the client fails to complete the TCP 3-way handshake with an ACK, instead the client resends the SYN.
The issue is that the server responses either don't reach or are not accepted by the client.
