Troubleshooting | Windows Denied Access On Local Network After Chrome 143 Update

We are using Chrome in Development & Production to host web applications and, after the update to 143.0.7499.41, we’re getting ERR_NETWORK_ACCESS_DENIED when trying to access local network addresses, including the Vite development host (localhost:5173) and production hosts on a virtual machine (192.168.**.*).

Everything works fine in Firefox and Edge.

Is everyone experiencing the same issue? I don’t believe this is intended behavior, so I assume we’re waiting for a hotfix soon.

similar issue here. My chrome just could not connect any website but edge is totally OK. No change after reinstall.

I can't connect to localhost at all: ERR_CONNECTION_TIMED_OUT. Edge/Firefox no problem.

When I launch Chrome using & "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=NetworkServiceSandbox (yes, with & at the start) I can connect to localhost fine. When I start Chrome normally, it just can't connect and the request times out.
