Gateway not configured properly when read_online_value

Here is what I use to read online the parameter value.

proj = projects.primary
app = proj.active_application
plc = proj.find("Device", True)[0]
onlineapp = online.create_online_application(app)
onlineapp.login(OnlineChangeOption.Try, True)
dev1 = proj.find("DEV1", True)[0]
for conn in dev1.connectors:
> parms = conn.host_parameters
> if len(parms) > 0:
> p = parms.by_id(1074855985)
> p.read_online_value(2000) ---> error: Gateway not configured properly
