PROTO_OA_GET_TRENDBARS_REQ taking to long to return data

I hvae a ctrader app that is requesting for trendbars for given symbols but the request is taking over 20 seconds to return the data for each symbol which is very long.

Is there an issue with the wss://demo.ctraderapi.com:5036 since all the other calls are under half a milisecond but the request  bar data is taking long even if i specify the count to be 5
