Recently got a new computer running Windows 10 Professional (using it on a company domain, running Sophos anti-virus). After installing current versions of both Chrome and Opera from Google and Opera (respectively), installing the latest version of Enpass from the Enpass website today, I am getting "Connection Error" in both browsers -- the error goes away and the plugins work as expected if I disable the option to "Verify Browsers". Obviously this is not as safe/preferred. I have disabled the Sophos antivirus and the issues remain. I have rebooted and the issues remain.
Please let me know if I can be of further assistance in tracking a solution down (I am running the plugin successfully on several other laptops running Windows 10 Home).
Thanks!
