RokuKast works perfect on some networks, not at all on others about rokukast HOT 2 OPEN

Same here. Roku detected in settings of rokukast, but no matter if it's at the roku screen (showing home, featured free, live tv, etc) or in youtube, nothing happens when I press the square icon to cast a video. This can be a direct link to a video (where it's just a black background, and you can right click and save the video in chrome). Nothing happens at all on the TV or on the program.

Roku 3930x - roku express
version 11.0.0 build 4193-ae
using latest wireless router (1gbps fiber line)

from rokukast.

I'm using same TV but just switched to a Nest Wifi setup and a new ISP. RokuKast no longer works at all, and it's a real bummer. Not sure how to move forward -- I'm casting to a Chromecast and it's so much worse. Any advice here would be hugely appreciated!
