Problems with garage automation

I have your system and all functions . I added garage door opener and it is synced properly when I send a signal to open and close it flashes and states opening or closing. But nothing happens. There are. 4 connections on my garage door opener I am not sure which 2 are the connections that are correct .

Are you using the 828LM Gateway and 888LM Control Panel or are you using the 821LM Universal Garage Door Kit?

From your question, it sounds like you’re using the former. Can you please provide the model of your garage door opener? Also, I’ve attached a compatibility chart. Please take a look at that and to make sure your garage door opener is compatible.
