Here is where the router comes in...

If the router signal strength is not enough to communicate with the doser, you will see longer load times.

One way to rule this out is to temporarily switch the SA Doser to LAN mode and connect an Ethernet cable to the doser and your router. If the speed improves, then that confirms the issue being signal strength related.


When you connect, have you tried comparing the speeds between connecting through your network vs. myGHL?
What were the results?
Did the OP see a resolution to this issue?

After a couple of weeks of problem free connection I too have difficulty connecting via the app.

My Doser SA and my (non GHL) controller are connected by WiFi to the same router at 2.4GHz.

I can connect to the cloud desktop for my controller every time in sub 3s.

Connection to the Doser vis GHL Connect if it connects takes much longer somewhere between 15s and never.

Ping time to the two servers is the same, myGHL server route goes through an additional hop but can't see that as significant

I can't see that this is down to my WiFi

BTW Red Sea leds and reef waves connect via cloud app every time without issue

Quite frustrating ....
