In My Arduino program reateTCP(HostName,port) return false

[NyanNaingTun]

My program is shown

setup begin
FW Version:AT version:0.21.0.0
SDK version:0.9.5
to station ok
Join AP success
IP:+CIFSR:STAIP,"192.168.1.104"
+CIFSR:STAMAC,"18:fe:34:f8:c0:39"
setup end

create tcp err

create tcp err

create tcp err

I don't know Why it cannot connect to TCP. Please help me?

Is it not connecting, or is it just saying it isn't? wifi.createTCP(HOST_NAME, 80) returns false for me too, but wifi.send((const uint8_t*)hello, strlen(hello)); still sends the data (sometimes).
