Unfortunately there is a current issue with macOS Sierra, we have a workaround here:
Sorry for the inconvenience, we are working on a more permanent fix.
I tried the link you suggested, however Firefox could not find anything at http://localhost/jaksta.cer.
I tried launching firefox before and after staring Jaksta, with and without monitoring enabled. Seems there is no certificate to open.
What exactly do you see when you click on the link while Jaksta is running? Are you able to send us a screenshot of what you see in Firefox?
We now have a beta version which should work properly on macOS Sierra:
This should work in Safari and Chrome. Let us know if there is still any trouble.
The new version seems to be working. I'll play around with it a bit more, but I can access the internet now with Jaksta running.
Thanks for the help!
Any time I try to start monitoring, my internet connection shuts off.
I am using Sierra, and just purchased Jaksta today (1.5)
I've attached my log file.
