RokuKast works perfect on some networks, not at all on others

I love RokuKast! When at home it works perfectly on my TP-Link AC1750 Archer C7.

But on the road the ability to cast the exact same streams is very much hit-or-miss -- and when I try there are always only two outcomes:

• On some networks I'm able to RokuKast streams successfully on 100% of my tries
• On other networks I'm able to stream successfully on 0% of my tries. On these tries, the TV screen does not change.

I of course always update RokuKast's settings by changing the "... or enter an IP address manually" field, then restart my Chromebook.

I don't know how to troubleshoot or what information I can collect here, but would be happy for any suggestions or advice. Thanks so much!

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.

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!
