I just bought HAP ac2 and made simple configuration as Home AP Dual, set WAN and LAN interfaces and WiFI.
Everything works well, I added some rules for gaming and QoS, but even without them just after getting internet connection I can't watch Twitch live streams.
Every other site with live streams work, I can watch VODs on Twitch, only live streams are black and I get Error 2000 after some time.
I checked on multiple devices and it is the same, checked directly on first router (that is about to go in bridge mode soon) and it works.
What is it about? Doesn't standard configuration allow some kind of packets or ports that twitch needs to work?
Tried changing DNS in RouterOS and PC to same as ISP router, because it is using ISP DNS, but no luck.
DMZ to my PC, nope, doesn't work.
