I have installed FME Core on windows machine and distributed engine on Linux machine. I am getting following error in my logs “ERROR : FME Engine failed to register with FME Flow 'FME-CORE-DEV' on port 7070. Failed to verify message authenticity” Engine appears on FME FLOW but it is not active and always appers as disconnected.

It’s not a situation I’m particularly familiar with, but my first thought would be firewalls and networking issues.

I’d also ask the question of is a remote engine better in this scenario than a distributed engine? 

They’re both similar, but interface back to the core in different ways. There’s some additional detail here:

I checked FME Core can communicate with distributed FME Engine. From FME Engine I can able to ping FME CORE.
