My kill switch is not working

I use a MacBook and I happen to use ExpressVPN. As far as I am concerned, I had to remove everything and start setting up afresh the moment my OS got updated to the latest Catalina. I’m sure you’d be able to resolve your issue if you do a hard core reset configuration of IPVanish on your MacBook. Also, make sure to check the ‘Kill Switch’ box in the Preferences Connection section once you’ve done re-installing everything. I’m able to use the Kill Switch feature and stay anonymous now. Try it out! I think it should work and hope I was useful at least in pointing you in the right direction.

Thanks for your advice. I'll give it and shot and let you know if it solves my problem.

I tried your suggestion, and IPVanish still allowed seeding and leaching from Transmission even with the kill switch enabled. I have removed IPVanish and all files from my Mac and am now using ExpressVPN without issue. message edited by HotJim
