Connectivity between Python and MT4 issue!

[Hosis86]

Hello,

I want to thank you for your fantastic work. I've newly downloaded and installed ZMQ and all it's dependencies and done all the steps you have explained in your videos (regarding libraries, include folder and the settings in MT4). I have no problem with adding the expert to the MT4 charts and everything seems to work perfectly. When I open the Python file (DWX_ZeroMQ_Connector....py) after initializing the code I try to subscribe to the pair EURUSD as an example. Whenever I try to call the subscribed data using _zmq._Market_Data_DB.keys() (as you mentioned in your videos) I don't receive any real time data regarding the subsribed pair and I receive only the following response: dict_keys([]).
Generally it seems that I don't have any connection stablished between Python and the MT4 but I don't know, what can be the possible problem. Can you please help me?

regards,

I musr add to my question that I've noticed that the PUSH/PULL socket works perfectly and I have no connection through PUB/SUB socket. I've tried to change the port but it didn't help.
