Tool/software: TI-RTOS
As the topic says I have problem with HTTPCli_connect when using static IP, but if DHCP is defined it works. I have checked the communication with the Wireshark and if I use static ip it doesn't even send anything with the HTTPCli_connect. HTTPCli_initSockAddr works perfectly, means it gets the IP address from hostname from the manual defined DNS server. Below the code.

if (ret < 0) {

}
Everything works if I comment everything out from the TcpHooks_vNetOpenHook. I have followed with the debugger from the HTTPCli_connect, which is not easy from optimized code, to place where it just can't find the route to the destination. What could be the reason?
