I am trying to access a list of subscribers that exists inside ET via your API calls, but am receiving a time out error (even when just querying a single list).

This seems to be some sort of performance issue on your side as the list is small (<20 people) but I have not been able to successfully retrieve it.

Here is the stack trace of the error:

  • Any help here? This is still a problem and I don't seem to have any way to resolve this issue. Commented Dec 29, 2016 at 1:59

I ran into this same issue. Try setting a larger timeout. This option isn't anywhere in the FuelSDK documentation. I had to dig into FuelSDK and SUDS source. SUDS default timeout is 90 seconds.


myClient = FuelSDK.ET_Client()

Hope this helps!
