[SOLVED] Async HTTP requests

Hello

I am trying to make an Asynchronous HTTP request by his code:

http = CreateObject("roUrlTransfer")
port = CreateObject("roMessagePort")
http.SetPort(port)
http.SetUrl("http://mysite.com") ' should return response in up to 30 seconds.

' SSL certicate, a must for HTTPS addresses !
http.SetCertificatesFile("common:/certs/ca-bundle.crt")

rsp = http.AsyncGetToString()
message = wait(0,port)
print message.GetResponseCode()
print message.GetString()
print message.GetFailureReason()

And it fails:
-28

Connection time-out


What is the reason for this ?

Thanks
