Send HTTP request contains IPV6

[MahdiBabaie]

Hello all
I have three devices. Two ESP32 and one PC. One of the ESP32 acts as a server for other two devices. Then we have:
1.ESP32 (Server)
2.ESP32(Client)
3.PC(client);
they are in a VPN connection so they are in the same virtual NAT and I am able to send request to server using its IP6.
When I do this using my PC every thing is ok and server respinses the PC. for example if my server has IPV6 like this 1111:2222:3333:4444:5555:6666:7777:8888 and I send request using my pc like this:
http://[1111:2222:3333:4444:5555:6666:7777:8888]/doSomething
the server runs the doSomething code but when I send the same HTTP request using ESP32(Clinet) I get error code -1 which means: HTTP ERROR CONNECTION REFUSED

Now what should I do to send success requests from ESP32(Client) to ESP32(Server) using IPV6.
Is this possible atall.
