Hi @Park,
Unfortunately, I failed to reproduce this issue on my side. But I can give you some possible workarounds:
- Go to Control Panel --> Programs --> Programs and Features, right click on Microsoft Edge and select Repair to repair Microsoft Edge.
- If #1 does not work, create another Edge profile and try to disable the flag in the new profile.
- If both of the above don't work, let's set this flag using the command line options:
- Close all Microsoft Edge instances first.
- Right click on Microsoft Edge shortcut icon --> Properties --> Shortcut.
- In the "Target" box, add a new command line option: --disable-features=BlockInsecurePrivateNetworkRequests. The result may look like this:
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --disable-features=BlockInsecurePrivateNetworkRequests
- Hit "OK"
- Now the flag is set via command line options.
Anyway, regarding the problem of edge://flags, I suggest you send feedback in both Microsoft Edge and Chrome to let Dev Team know about this problem.
