Can't connect Pabbly mail to Amazon AWS

Hey guys,
I've followed all instructions to connect Pabbly mail to Amazon AWS.
I've used Pabbly's templatte, but every time I create a stack, it ends with the status "ROLLBACK_COMPLETE" which means the stack has not been created correctly.
Any ideas!?

Hey,

Greetings from Pabbly!!

Hey tverdouw, i follow you on youtube - great job!

Funny to see you here and I guess it was a good decision to switch to Pabbly Email? Because if you decide that, then that means a lot :-) ?!

Have a good day
