Integration Gateway: General Connection Failed (158,10836)

Hello everyone,

I have a server with two domains (1FSCM and 1HCM) .

My gateway is well configured (Success after pinging it)

I added the two nodes to it (PSFT_EP and PSFT_HR).

I configured them on both applications (Local/Remote).

I can ping them both on FS with Success, but on HR, I can only ping PSFT_EP, when i try to ping PSFT_HR, it takes 5minutes and then i get this error message : Integration Gateway: General Connection Failed (158,10836)

Note that I followed all the solutions posted in Oralce Support but still can't resolve the problem. The URLs are correct, the passwords too, Keystore is configured too on IntergrationBroker.properties...
