iTunes Home Sharing is not working with Privacy engaged

[Jetsman]

Hello,

I am running Windows 10 (20H2 Build 19042.685) with Privacy version 2.3.0.462. When I have Privacy on, my Apple TV cannot connect to iTunes running on my PC to use Home Sharing to access my library. If I turn Privacy off, everything works fine. The iTunes version is the latest from the Microsoft store.

Any thoughts?

Thank you.

Is the following setting on? If so do the following.

Can you please collect and upload as an attachment the diagnostic data using our MBST?

• Download and run the Malwarebytes Support Tool
• Accept the EULA and click Advanced tab on the left (not Start Repair)
• Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

 

[Jetsman]

Yes, that setting is on. I've attached the ZIPmbst-grab-results.zip here.

[Porthos]

Is the kill switch been enabled? be sure it is off.

[Jetsman]

Yes, the kill switch IS enabled. Do you mean shut it off for the data collection?

[Porthos]

Turn off the kill switch and see if I tunes works.

[Jetsman]

Yes, it does work without the kill switch engaged. Good thinking, though this should be fixed in a future release.

Edit 12/23/2020 - the kill switch is also preventing me from using my network printer (not attached by cable).

I notice you installed Cisco Jabber just a few days ago. Is it possible your issues started after installing Cisco Jabber?

Using the support tool, I inadvertently selected the option to repair my software. I guess this reinstalled MalwareBytes. Since doing that, my PC is acting strange. But I also uninstalled Jabber to see if that resolved my original issue. So multiple things are in play here.

BTW, I had the same problem on another PC during the trial. And in that case Jabber was on the PC first.

Thank you for your help on this.

[AdvancedSetup]

You can use our MBST tool to fully remove Malwarebytes but I'll probably need to get a new FRST log after that to help you remove a few other files as the MBST tool has not been updated yet for a few of the Privacy VPN file removals.

Run the MBST tool, do the removal and restart but do not allow or choose the reinstall of Malwarebytes yet.

Then run FRST and get logs and we'll go from there.

 

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system.
You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). Please attach it to your reply as well.

Thank you

Things are now so fubar that I’m reverting my PC to restore point from a week ago. Will be back in touch when things stabilize. One thing I did notice is that Privacy seems to kill the Bonjour service from Apple. Without that, Home Sharing will not work.

[AdvancedSetup]

Home Sharing is not dependent on Bonjour. Home Sharing uses protocols from Microsoft, and / or standardized protocols. Bonjour is an Apple product they use for network discovery.

Sharing Apple TV or iTunes to another Apple device may require Bonjour but users without Apple products can and do share home networks and data all the time.

Not sure how removing Malwarebytes would have altered or changed the computer though aside from restoring some resources. Has the computer had a history of instability?

I'm officially out until the new year but post back and let me know how the restore went

 

[Jetsman]

Thanks for your post. Let me differentiate between home sharing (sharing on your home network) and Apple’s “Home Sharing” between iTunes and Apple TV. I’m referring to the latter, which does use Bonjour, and works fine without Privacy engaged. I’ve been using it for years, and don’t want to look at alternative file sharing methods just because of an issue with a new product. Let’s fix the issue, assuming there is one.

After a system restore, my PC is again working fine. I have a new restore point set and an up-to-date image saved so I can experiment a bit. I’ll reinstall Privacy and let you know how it goes.

[AdvancedSetup]

If it does not work then we'll need to look at it closer, but due to Holiday, Pandemic, Vacations, etc. there probably will not be any product updates out until well after the new year

Thank you

Was this resolved? I'm having the same issue. I have to uninstall Privacy completely before I'm able to use the home share feature again. I just purchased Privacy today and haven't downloaded any programs besides that on my computer so it definitely has something to do with Privacy. I'm using latest Windows 10 update and latest iTunes/Apple TV iOS software.

Thanks

[Jetsman]

I haven’t had a chance to re-test. It’s a bit frustrating that this is dependent on me. How hard would it be for someone from MalwareBytes to test this scenario?

I’ll try to get back to it.

[NunChukaKata]

No need to rush or think it’s solely yours to figure out, I was just curious if any progress had been made since it’s been a month when the last response was posted. It would be easier if a Malwarebytes tech could give feedback. Thanks for the response 

[AdvancedSetup]

I don't own or use anything Apple so yes it is difficult for me to test. I also don't share anything with other computers. I isolate my computers on purpose.

That said, I am more than willing to work with you and if needed engage someone from Quality Control that may be able to duplicate this.

If you're willing to work on it with me I'll be happy to assist, just let me know.

Thank you

 

[NunChukaKata]

I have an assumption. Home sharing is reliant on the devices being on the same network. Once you install and activate Privacy, it makes another active network (the malwarebytes vpn) on my computer and appears to kick off my normal wifi causing it to show no internet access. Since it does this, I'm assuming the Apple TV doesn't see it as being on the same network anymore causing the issue. So I'm guessing if there was some way to connect the apple device to the mbvpn network on the computer (or allow the normal network to still show access in a home network), it would fix the issue. You can see the active networks in the screenshot. I may be incorrect with my assumption, but it does make some sense. Thanks

There is now split tunneling.

 

[NunChukaKata]

I had already tried adding the IP of the apple tv to the list but still couldn't get it to connect back. Unless there is another stop, it may not be a resolution. Thanks

Add I tunes software/.exe's to the bypass VPN section.
