Please check details of the packet. That is what is proposed by the client. The question WHY is not something Wireshark will be know. That is up to the application and it's config.

issued connection by Ethernet adapter with Firewall - https://imgtr.ee/i/OiQSL
details of TLSv1 line - https://imgtr.ee/i/OiTA0
retransmitting issue - https://imgtr.ee/i/OiYzF
reset, ack - https://imgtr.ee/i/Oimam

also I've tried via WiFi-adapter (another internet without Firewall) - https://imgtr.ee/i/OirFB where watsapp is working with no problems
