Problem with Chrome extension

Hi,

I am trying to get Enpass working on a clean install Windows 10 laptop. I'm using the Enpass install from the Windows store and the Chrome extension from the Chrome store. When I click on the extension icon in Chrome, it displays the "looking for Enpass" page and if Enpass isn't it then launches it. But then it errors  with "Enpass Assistant is unable to connect with the Enpass app."

I initially suspected that the Sophos antivirus on the laptop was interfering with the comms to 127.0.0.1 - BUT, Enpass works just fine in MS Edge (using the Edge extension) and also Vivaldi (using the Chrome extension from the Chrome store!!!!). I really don't understand what's causing Chrome to fail, especially as Vivaldi works...

Enpass version is 6.1.0 (408) and Chrome extension is 6.0.2 - If it helps, Firefox behaves exactly like Chrome.

Thanks.

I've had to split my message as the message checker doesn't like me and/or code boxes :( ...

If I enable logs in the extension I get:

Enpass is definitely listening on port 10391:

 Enpass.exe                   12008 Console                    1     87,848K

Hi @Mark923,

Sorry for the trouble you are going through.

I would like to share that Enpass app communicate with the other browsers (Chromium or Firefox based browser) via localhost address (127.0.0.1). Although  Enpass extension for Edge browser communicate with the main app via NMHost that's why Edge browser extension is working fine and other browser is throwing Enpass connection error.

So please bypass the  localhost(127.0.0.1) connection from Sophos Antivrus and let me know if the problem persists.

Hope this helps!

Thanks for giving an insight why MS Edge works - I wondered if it used a different mechanism. The Sophos on this PC is managed centrally, so I can see if I can get the IP/port opened. *but*... what completely confuses me is that Chrome does not work whereas Vivaldi (which is based on Chromium and actually uses the extension from the Chrome store) *does* work.  If the IP/port was being blocked by Sophos, then Vivaldi ought not to work, as it's using the same approach as Chrome. But it does...

I encountered this, again, for no apparent reason.  Enpass was working fine one day.  The next, I started getting this message in a tab in Chrome every time I opened a new browser.  Looking in the Browser section of Enpass, where I expected to see Chrome, it's path and an "authorized" icon, I saw nothing.  There appears to be no rhyme or reason to why this happens.  My frustration with having to wait two business days, minimum, to get a response forced me to uninstall the app and the Chrome extension.  Once that was done, I rebooted and reinstalled both.  The sync to my vault happened and I authorized the browser.  All is working now.

Even though I have it fixed, this seems like a prevalent enough problems that there should be more attention given to it.  Uninstall/reinstall is not an exceptable long term resolution.  This has been happening for a while and Enpass should get to the bottom of why the extension disappears and the connection fails.

It happened again.  I've been seeing this problem every few weeks for a while.  Very frustrating.  I opened a case and was asked to grab a bunch of different log files, which I can't recall.  I got the thing working by deleting everything and reinstalling, but my patience is wearing thin.  May be time to start looking for another product.  Rebuilding every week or two is untenable.  

Windows 10 1809

Chrome Version 77.0.3865.120 (Official Build) (64-bit)

Enpass Password Manager extension for Chrome
Version 6.0.2

Enpass 6.2.0 (542)

Could you please let me know how to bypass the localhost, when in a managed sophos environment? In my sophos endpoint there's no "protection" tab to make the exception.

  • On which device (along with OS version) are you using Enpass? WINDOWS 10 PC, version 1903
  • Which Enpass and Enpass extension version are you using? Enpass version 6.4.1 (642), browser extension for chrome version 6.4.0
  • Which Chrome version are you using? Chrome Version 81.0.4044.129
  • Are you facing the same problem with other browsers too? No, Edge, Vivaldi, Opera work fine.
  • Are you using any Antivirus or third-party security-related extension? Sophos free antivirus
  • Also, let us know the error you getting? Well, I use it in Dutch version, so the exact error is "Verbindingsfout! swi_fc.exe voorkomt dat de Enpass-extensie verbinding maakt met de Enpass-app.", roughly translated to: Connection error! swi_fc.exe is preventing the Enpass extension to connect to the Enpass app.

I already tried the solution described at "https://www.enpass.io/support/kb/security/enpass-browser-extension-is-not-working-due-to-sophos-antivirus/".

The local adress is excluded in any possible way, but I still get the error. Furthermore, this doesn't make sense, as other browsers (Opera, Vivaldi) have no problem. I understand Edge works differently, but Opera and Vivaldi work the same as Chrome I believe?

Please advise @Garima Singh .
