Can't access aicloud over the internet on RT-AC66U

[Nippon_Ichi]

I've been trying to set up aicloud and smart access to access my shared windows folders remotely on my RT-AC66U with the latest merlin build. Currently this works perfectly when connected to the network but when I try over the internet on a different connection I get nothing; just connection timed out in the browser or similar in the aicloud app. I've tried forwarding ports 8082 and 443 but no luck. Googling has also failed to produce a solution so now I'm asking here. Please help me!
