Incident ID: 2837375727260943326
Place ID: 95206881

I have uninstalled roblox, restarted the machine, re-installed roblox.
Tried several ways of “editing” a roblox place.
But clicking “start local server” makes this error every time.

Expected Behavior

For the studio to open a local server.

Actual Behavior

First, you get this window.

Then you get this in the studio.

Workaround

Went into Windows restore, canceled that, and restarted the machine.
Restoring the machine to an earlier stage could also fix the issue.

This issue has already been reported:

Failed to start network server, port: 53640, error: SOCKET_PORT_PRIVILEGED

Reproduction Steps The bug (for me) first appeared on 11/26/2021 at about 10:00 AM EDT. I disabled all beta features (but at the time the bug happened the Pivot Editor and Parallel Lua were enabled). I reinstalled studio and removed all plugins, but this didn’t fix it. Neither did the disabling of beta features (and I restarted studio after I disabled the beta features). This happens in team create and locally. System information Motherboard ASUSTeK COMPUTER INC. ROG STRIX x570-E GAMING …

In 2021 and closed i know.
I got it today.
Never had that problem before.

And yes I did check that post before posting this one.

I have also made sure that I don’t have that port active at all.

Thanks for the report and sorry for the late response. Are you still experiencing this issue?

[Master3395]

Hello.

I ended up having to revert my whole PC back 1 day, to an earlier Roblox installation.
I then uninstalled Roblox, and removed Roblox from all regedit strings.
Then restarted the PC.
Then re-installed roblox, and it works.

Hello, the issue still occurs on my end:

It only happens on my laptop, never happened on my desktop before. I’m not sure what information I should put here, but I have gotten this error about 5 days ago and it’s still happening on my end, and only with my laptop.

[gigagiele]

I see. Thanks, I filed a ticket to our internal database and I’ll come back with updates when possible.

[Master3395]

Any solution to this problem?
It happen again today, when I tried starting studio in test mode with 2 players.

I also tried starting it with 0 players, and still got the same error.

Sorry, this place could not be loaded. Details: “Failed to start network server, port:53640, error:SOCKET_PORT_PRIVILEGED”

Hi,

I’ve been experiencing this issue here and there and I finally got tired of it, enough to look into it.
Roblox statically uses port 53640 to start a server in a local multiplayer test, which is fine except it doesn’t check if it’s already reserved.

This usually isn’t a problem unless you have services/applications that reserve these ports such as:

WSL
Hyper-V
Windows Sandbox
Docker for Windows / Docker Desktop

If you are a user affected by this you can do the following to work around this issue:

Open a command prompt window as an administrator and run the following commands
These may mess with utilities I listed above (and maybe more) so run with caution

net stop winnat
net start winnat

To verify that the port is now open run the following command

netsh int ipv4 show excludedportrange protocol=udp

The other option is to just reboot your PC and hope that it doesn’t get the range reallocated.

Demo showing the issue being resolved:
(EDIT: I accidentally highlighted the wrong range, ignore that and look for the range yourself)

Hey guys! Thanks for reporting this issue.
Happy to share that we recently patched this, so you should no longer run into this issue.

Please let me know if it ever returns
