Hi guys, Sorry to hear about your trouble. I would like to let you know that Enpass browser extension communicates to Enpass app over the localhost address. So please check and verify that the installed Antivirus/ Firewall is interfering the localhost connections (127.0.0.1). Also, share these details Have you installed any Antivirus/ Firewall/third party any security related browser extension? Are you using any proxy? Are you facing the same problem in other browsers
