This question already has an answer here:
I'm using Tor (v 6.0.6 (based on Mozilla Firefox 45.5.0)) on Mac Sierra. I realize the behavior is largely unpredictable, but what are some possible reasons why requesting a page in a Tor browser woudl result in a 403 or "Unable to connect" message whereas it is easily accessible in a Chrome/Firefox browser? An example is I'm never able to visit htis page -- http://www.plattsys.com/m1shell.asp?eventid=1080 , in a Tor browser and trying to think if there are any configurations I can make that would make my Tor browser behave more like the other browsers where I can access this page easily.
Thanks, - Dave
