Fing Desktop won't list devices

datagod

My Fing Desktop seems to have stopped functioning, even after manual service restarts and full computer reboots.

I am running Windows 10, AMD 12 core Threadripper, 32GB Ram.  I am connected via ethernet cable to my local network.

I see this error in the logs:

Fing desktop is not compatible with any applications which require NpCap library like Wireshark.

@datagod, assuming nothing has changed in your PC configuration since it was working, try disabling hardware acceleration.  Its in the preferences section and will require you restart the Fing app.  let us know if this work...

datagod

I disabled hardware accelaration and restarted the service and the app.  Still getting the same behavior.

Thanks for the follow up. Let me tag @Robin from Fing to see if he can help out.

In the interim, can you also run this command at a dos prompt and let us know the output? Looking for the status of ncap, which Fing needs to do it’s thing.

I am using F-Secure firewall/antivirus/security, which seems to be quite aggressive lately.  I didn't get any alerts from it about Fing, but I am suspecting it may be at fault.  I'll disable it and see if that helps.

The antivirus could be the reason for Fing desktop not working. Can you reboot your computer in safe mode with networking and then check if the issue persists or not? Thanks

datagod

Rebooting into safe mode did not help.  I also tried installing on an older Windows 7 machines, I get the exact same issue.  Could this be a router/network issue?  I am using OpenWRT on a Linksys WRT3200ACM router.  I am also using PiHole for DNS.

I have been using that network setup for over a year however, and Fing was working just fine.

Here is a recent error in the windows eventlog.

To rectify this, if you have another router or you can connect fingbox to a different router then we can isolate if the router is issue.

@datagod
For the error, I can see the Faulting module name: MSVCR90.dll which happens when you have WinPcap and NpCap installed together and causing a conflict. I would advice to completely uninstall Fing desktop using Revo uninstaller or look for the location of Faulting module name: MSVCR90.dll and delete it. After that reboot device and install Fing desktop again and it will resolve the issue.

datagod

I did all that, uninstalled NpCap and WinPCap, re-installed just WinPCap, re-installed Fing desktop, rebooted, etc.  Still not working.  Is there any way to fire up the Fing.Agent service is a verbose / debug mode?

Well, after purging and re-installing several times, 20 reboots, examining the router, the network settings, evertything I could think of I have just simply given up ever running Fing desktop on my main computer.   I remembered there is a mobile app, so I used that.  It works great, eliminating the router as a possibility.  I'll just chalk this up to DLL hell.

I will install on a different computer on my network and simply move on with my life.

datagod

The saga continues.

On a windows 7 computer, I uninstalled anything to do with wireshark,  nmap, etc.  I then installed npcap1.5 (failed to start) then npcap 1.31.

I rebooted, installed Fing desktop, rebooted again.

Now the error I am getting in the Fing.agent log:

ERROR 2021/07/13 12:07:17.186 === fing agent 2.6.0 - www.fing.io ===

ERROR 2021/07/13 12:07:21.353 HeartBeatEngine | Unable to generate network signature: cannot find gateway MAC

ERROR 2021/07/13 12:07:28.881 RouterNatPmp | Exception : Unable to Receive NATPmp message : The I/O operation has been aborted because of either a thread exit or an application request

My network connection is definitely active.  Fing says it can't connect to the internet but still does a bandwith speed check.  Also the main health checks pass.  Router check passes.  Everything except "list devices" which is still complainiing that there is no network.

I am connected using ethernet cable, not wireless.

Is there any debug/diagnostic I can turn on at the service level?  I believe the problem is with Fing.Agent service.

datagod

I installed Fing desktop on a clean install of Windows 10.  It worked.  I wish I knew what the dependencies are, but I guess that will never happen.

datagod

The strange part is that it was working fine for 6 months then stopped working.  The errorlogs need to be a lot more verbose.  Including helpful hints such as "make sure your computer has never done anything with Wireshark".

datagod

The never ending saga  continues.  The clean windows install that I put Fing on...well it worked for 1 day then stopped working.

I think it is clear by this time that Fing 2.6.0 is the culprite.  It is just too unstable.  

datagod

@Robin can you please review this thread and give me some advice?  I have a premium subscription but I don't see the value of it anymore without the desktop application working.

To sum up:  
2.6.0 stopped working on my main PC.  I made no changes.

I followed your instructions to cleanly uninstall and re-install, made sure there were no other versions of npcap or wincap installed.

No luck.

Then I installed on a clean version of Windows 10 and it worked for a day, then stopped.

I have spent dozens of hours troubleshooting this.

Is there any advanced diagnostic logging that I can enable to see what the exact problem is?  If not I'll have to cancel my subscription.

@Robin I have replied to the email, and sent the screenshots as requested.  Any ideas on what is causing this issue?
