Chrome not able to access local network, LNP issue

I had this in November 2024 and nothing would fix it until one day, by fluke, Chrome asked me if I wanted to allow access to devices on my local network. I'd never noticed this before but after I clicked Yes to this, I could access a URL on my local network. Today however access suddenly stopped working and I cannot see how to get Chrome to ask me that question again. So far I can see no setting to adjust to make it work again, so I have to use Safari for now.

Continues to be a problem and still no resolution.

Edit: I misread the main post. This fixed my issue, but likely isn't the issue you're all seeing. I can't delete this post so unfortunately it has to stay.

Just in case anyone comes across this and needs the answer.

Go to System Settings => Privacy and Security => Local Network

You should see that the slider for Chrome is unset. Go ahead and set it to enable local network access again.

You don't need to reboot or restart your browser for it to work.

This is mind boggling. I have accidentally said 'no' one of the times I saw this message about Chrome needing permissions to access the local network. I didn't think of it much, as I know this question appears constantly (after each update to Chrome in fact and Google seem to update their browser for unknown reasons almost weekly) End of the day its the same browser we put up with, since it seems to be used by many other people! Once I said 'no' there is no force on earth able to reverse this decision. Absolutely amazing how Apple builds software nowadays. You can toggle all the instances in Chrome in your Privacy & Security -> Local Network. This does absolutely nothing for me. I have to wait for some random event of Chrome asking again for permissions. Even if I answer 'yes' the next update of Chrome in a week breaks everything again. How do normal developers operate in such circumstances I have absolutely no idea.. Do we need to have 2-3 Macs so that one of them actually works?!

I was able to fix the problem, but there is no guarantee that it will not come back. After further researching I found this and it does reset LNP. This will remove all of the double entries and reset Chrome so it will ask to allow access to devices on my local network. Hope it helps others.

1. Start up your Mac in recovery mode
2. Disable SIP by opening terminal (in menu bar under utilities) and enter crsutil disable at the prompt
3. Reboot
4. Delete the following files
   1. /Library/Preferences/com.apple.networkextension.plist
   2. /Library/Preferences/com.apple.networkextension.uuidcache.plist
5. Reboot
6. Relaunch Chrome and verify you are prompted (remember to answer yes, ;-)) and local network in settings is clean with a single entry
7. Shutdown and start up Mac in recovery mode
8. Enable SIP by opening terminal (in menu bar under utilities) and enter crsutil enable at the prompt
9. Reboot

Please use if you are comfortable with how the OS works, but use at your own risk. Hopefully Apple/Chrome will address issues in upcoming releases.

This is how I manage to fix it.

1. Close completely Google Chrome, I've made it by forcing
   1. Cmd + Option + Esc
   2. Select Google Chrome from the list
   3. Force quit
2. Got System Settings -> Privacy & Security -> Local Network
3. Uncheck any of the Google Chrome slides, that will uncheck all at once
4. Uncheck also Google Chrome Helper (GPU)
5. Enable again any Google Chrome and Google Chrome Helper
6. Open Google Chrome and navigate to any local address
7. The popup will appear to ask again the permissions

Same here. I opened a ticket in the Chrome Forum and with Apple. No feedback yet

Just to say that yesterday, 11th January 2025, I started up Chrome to do something other stuff and within a minute a dialog box popped up to ask if I wanted to allow access to devices on my local network. I clicked on Yes and now it is all working again. I've no idea what made it pop up that dialog box, but it could have been me connecting to the network using Ethernet when previously I was on WiFi. Not sure, but something triggered Chrome to just pop up the dialog box after starting up Chrome.

I'm having the same issue and situation as the OP.

As a workaround, I downloaded the Chrome Beta ( https://www.google.com/chrome/beta/ ). The beta version is seen by MacOS as a different app. During launch, it asked for local network access to which I approved, and I can now access local network services. This is only a workaround.

I'll try the Luv2ride11 solution if the Beta stops working as well.

Please fix this issue. I am a developer who mainly uses Chrome and I often have to use the internal network at my company. Because of this issue, it is very difficult to detect bugs. Please, please, please.

Hi there, yes, that it what seems to happen to many of us... But you should also see now several entries as in the picture above... makes no sense! Good it is working for you again now.

Thank you so much that fixed my problem

I forgot to update all of you about that... apologies. I am using Chrome bata for weeks now without having issues, besides knowing the sword of damocles is just bouncing over my head :-)

Confirmed working on 2021 m1 MBP 14 in. On 15.3.2 and latest chrome. Though it is csrutil.
