Fing has become increasingly unreliable the past few weeks.  

On my Mac:

1.  Often I get "can't connect to fing service".
2.  Right now I get "No internet" even though I obviously have internet as I am writing this

Website:

I only see 2 devices (I have ~30).  It says that 192.x.x.x my iMac Pro,  is on-line but that is not its IP address

After running the IOS fing app it started showing some devices but with really bizzare IP addresses - 172.x.x.x in addition to the 192.x.x.x. addresses.  Checking the associated devices that is not their address at all.

IOS Fing

On my iPhone 12 Pro Max, latest IOS, Fing just crashed.

After the 3rd or 4th crash for some reason it started working.  After it refreshes it shows 56 devices, some of which haven't been on the network for many months.  It also incorrectly shows devices with 192.x.x.x addresses.

Glumping multiple issues into one post isn't a great idea, but I wanted to show how Fing is now almost totally unusable.

    Hi @Caprichoso

    In order to address this quer for Fing desktopy, first I would like to confirm that you are:

    • Installing the Fing Desktop under the 'Applications' folder only. If not, Fing Desktop won't be able to connect to its services. If it is not, it will appear as 'Unidentified' or ‘Undefined.
    • If you have "Service not found" error, the service might have been disabled and cannot launch until the service is re-enabled. This is likely the result of the service having been unloaded using 'launchctl' in conjunction with the -w switch. This will disable the service. This condition can remain, even if the software is uninstalled and reinstalled.

    To resolve:

    Re-enable the disabled service using the following commands:

    • sudo launchctl load -w /Library/LaunchDaemons/com.fing.service.plist

    For Fing mobile app, if you are running Fing app on Apple device then please refer to this article: https://www.fing.com/news/private-mac-address-on-ios-14

    Installing the Fing Desktop under the 'Applications' folder only

    Yes

    sudo launchctl load -w /Library/LaunchDaemons/com.fing.service.plist

    iMac-Pro:~$ sudo launchctl load -w /Library/LaunchDaemons/com.fing.service.plist

    /Library/LaunchDaemons/com.fing.service.plist: service already loaded

    sudo launchctl unload -w /Library/LaunchDaemons/com.fing.service.plist

    sudo launchctl load -w /Library/LaunchDaemons/com.fing.service.plist

    Load failed: 37: Operation already in progress

     Fing was never loaded.

    Where are the log files kept in Big Sur?

    "Internet is not reachable" is current status.

    Don't need to close the agents.  It normally runs ok after a reboot but then fails.   So now fing shows no connectivity, with the added message:
    Your have warnings in your device configuration. Health check code: W008.
    but of course I do since I am writing this.

    Does the warning remain if you manually run the scan again? Can you please follow these commands on the terminal?
     
    Command 1: /usr/bin/pgrep fingagent 
    Command 2: sudo lsof -nP -iTCP:48080 -sTCP:LISTEN 

    On running the 2nd command, it will ask for a password and you need to enter the login password of your MacBook 
    After the 1st command, it will return a number example: 0000. You need to use this number in the command given below.

    Command: sudo kill -9 0000(result of 1st command)
    After this, can you reboot your device and then check if the issue persists?

    OK. I tried all that, nothing helps.
    The only thing that helps is switching of VmWare. 
    Then it all works again.
    So somehow VmWare interferes with Fing. What is that?

    The first command gave me two results:

    /usr/bin/pgrep fingagent

    893

    26855

    but the kill only worked on the first one

    sudo kill -9 26855

    kill: 26855: No such process

    Rebooting won't make a difference in that it usually works after a reboot, for a while ....

    Could the dead process (26855) be causing the problem?

    A bit later it was gone, but the agent had relaunched:

    /usr/bin/pgrep fingagent

    83863

    iMac-Pro:~$ sudo kill -9 83863

    Password:

    iMac-Pro:~ 

    and it came back again ...

    Guess it keeps relaunching itself ...

    You can also check under Activity Monitor if multiple Fing agents are running then you can quit all those Fing agents and then reboot your device and open Fing desktop again to see if it is working now.

    After several more failures we are going in circles here.  Yes, after the reboot Fing works.  Then it fails.  I can't keep rebooting every few hours as it causes problems with my backups as some restart scanning which can take days.

    How do we diagnose the problem of:

    1.  Why do I have 2 agents?
    2.  Why is Fing saying it can't find the service?
    3.  How can I restart fing without having to reboot?
