ServerCommunicationError when trying to use testserver mode

Hi,

I have succesfully tested my application on simulated mode having following lines in TEST_MODE.TXT:

[simulation]
default=simulated_ok

Purchase can be done without any errors. But so far I haven't been able to do any purchases using testserver mode, I cannot even get the product data. Here are the responses:

iap_client->getProductData("id");
->
[Qt Message] "SERVER => CLIENT MESSAGE: Message id: PRODATA, Request id: 4, Status: ConnectionError"
[Qt Message] Error in the productInformationresponse

iap_client->purchaseProduct(id, IAPClient::ForcedAutomaticRestoration);
->
[Qt Message] "SERVER => CLIENT MESSAGE: Message id: PURDONE, Request id: 5, Status: ServerCommunicationError"
[Qt Message] IAPClientImpl::socketReady(): Request 5 , status= "ServerCommunicationError" , purchaseTicket= ""

I have tried all the test mode settings without any luck. For example:

[testserver]
testMode=normal

Any ideas what I have done wrong? Do I need to somehow modify the purchase items at publisher page to be able to use the testserver mode?

Thanks in advance : )

Make sure that in your TEST_MODE.TXT file you only have the following lines:
[I][testserver]
testMode=purchase[/I]

and make sure your phone has internet connectivity and nothings blocks him from connecting to the internet (like a firewall or blocked ports etc)

Hi,

Make sure the device is able to connect Internet -- use browser to check connectivity. If you use wifi connection make sure SIM card is inserted into device. In case the problem still persists please provide more information.

I re-checked currently available IAP -- cannot reproduce the problem. The advice of having "testMode=purchase" option does not affect on ServerCommunicationError --- you can use any of available test modes for purchase simulation and real user authentication.
