Seems like they are using CGNAT, which means you won't be able to connect to some peers who are also not connectable due to both closed ports. One must open their port to establish connections.
They can surely remove you from CGNAT but for extra cost. I think paying for seedbox is much cheaper.
Even if it's 720p should beat the dvdrip version so just download it using streamfab.
The 1080p if it's available on MAX then it will come eventually. I already saw 720p web-dl.
