Harmony Hubs not found

I followed the Setting up your SmartThings with Logitech Harmony instructions page, but on the step 3 only show “(0 found)”, not “(1 found)”.

Everything works good on the Harmony side, but I can not have the option to select the Harmony Hub to go ahead with the setup.

I am at this point for two days, I deleted everything and started again three times.

I am working with a Logitech 915-000238 Harmony Home Hub, firmware version 4.2.48 and the app version 4.0.4/build 26.

Any help will be appreciated.

My experience is that the SmartThings side of the integration is broken more often than it works. There is always a fix on the way though. More in this thread Actions not showing in Harmony Hub Control
