Remote gate opener: relay replacement, remote control works, Supla only sometimes

Remote gate opening - problem,
the relay as in pictures 3 and 4 (small square cube 3 inputs, 1 black relay) has broken, so far opening the gate with this relay has been done by remote control as well as the supla app over wi-fi from the phone. I have replaced this relay with the one as shown in pictures 1 and 2 (rectangular cube 6 inputs, two blue relays), on setting the plugs as shown in the picture the supla worked only a few times and then stopped working and only the remote controls remained working, when using the supla you can hear the "click" sound of the contact but it does not open the gate.... On other plug-in options, only the remotes work, on another the supla itself, but only a few times then it stops.... strange thing:

.
The last two pictures show the picture with the first relay, it looks like it got damaged because all the piots and supla stopped working:

.
What could be the reason that the supla doesn't want to cooperate or it only cooperates the first few times and then you only hear a "click" when the signal is given, but it doesn't open the gate.... ?

I would appreciate any help, guidance,
Luke

The best thing to do is to draw a diagram, because you have two radio receivers and a supple, and no one is likely to see the connections from the pictures.

The faulty relay, as in photos 3 and 4, is unplugged, no longer in the circuit (old photos for reference).
