Running Unity 5 Gives Error, Drops Internet Access.

When i open a new Unity 5 project i get the error:
"Socket: bind failed, error: An attempt was made to access a socket in a way forbidden by its access permissions.
(0)"
And then my internet drops. (I still have a network connection but all internet connected apps get disconnected and my browsers gives a error when i try to browse).
15 seconds after i close Unity, my internet works again.

Should be noted that Unity 4.x works perfectly on my machine.

 

Realised that there are a few posts about this:

http://forum.unity3d.com/threads/unity-5-makes-usb-network-adapter-stops-working-properly.307951/

 

And we have all been collectively given a big middle finger so far.

Is this a new undocumented productivity feature, meant to force us to work on the bloody game instead of wasting time on the internet?

 

Tried reporting it as a bug using the UnityBugReporter.exe, not sure if it works outside of the Unity Editor though.

What is the case number you were emailed? I'll ask the QA team to take a look - you're a Pro customer, right?

 

Same error message here on my PC/Windows7 :


but Internet is working without any issues.

Can we get some more infos about that problem?


Best regards.

 

Looks like you are a Pro user. Can you PM me your serial. The editor makes calls back home to check for updates. I can look and see if the editor's connections are received.

 

Stupid question for those who encountered the problem: Do you guys have Steam open when launching Unity5?

I occasionally had the same problems but not always. Just now I tried opening Unity 5 and it worked perfectly fine. Then I started up the Steam client and reopened Unity and the Internet connection stopped until I exited Unity.

I have yet to test if this is a constant problem and whether it happens all the time.

(edit) sorry ... nevermind. This wasn't the problem, either.

 

Well, I've successfully isolated and fixed the issue on my part. Something networking related within Unity 5, or perhaps within Mono itself, triggers a bug in a driver for certain cheap USB wireless adapters, in particular the default driver that comes with Windows 7. Most other user's reports seem to confirm this, given that almost everyone I asked also happened to be using a dongle for internet access.

My card (or rather, its guts) happens to be Realtek's RTL8187B. Updating the driver fixed the issue, and now I can safely run Unity without losing my wireless access. (I was already looking for ways to sandbox/virtualize the damn thing just so it wouldn't break the network)

I'm kind of glad that the problem turned out to be something that's so easily fixable on a user's part, as opposed to something we'd have to wait for to get fixed. I lost all hope when 5.0.1 rolled out and the issue was still there.

To everyone affected, update your wireless drivers (make sure it's the latest ones from the manufacturer) and report back.

 

I'm having the same issue and neither updating drivers nor any of the other fixes from the previous threads are solving it. It appears that Unity 5 is exhausting all available TCP/IP ports, preventing my computer from making any new connections. It happens as soon as I load the editor, regardless of project. I reported a bug last week but haven't heard anything yet...

This is preventing our studio from upgrading to Unity 5, so I'd appreciate any other workarounds anybody has discovered.

 

Hey, I can send you my serial but looks like it's working fine now.
Error message is no more appearing in my console.

Best regards.

 

Hi. I just want to confirm that I am also getting this behavior after upgrading to Unity 5. I'm using Windows Vista 64bit and my USB ethernet adapter is the Asix AX88772. I have gotten the latest OS updates and drivers, but this problem persists: A few seconds after opening my project, my internet connection completely goes out. I have to close Unity entirely and reset the adapter in order to get back on the internet. Has anybody found a solution?

 

No solution here yet. No response on my bug report either...

 

I'm not using a wireless connection.
I have a cable modem directly wired to my computer.
Motorola SB5120

 

I've prodded them.

 

I just updated my network adapter driver. ( Realtek 6168 )
The problem continues.
The only difference now is that it takes longer for the connection to come back after shutting down U5.
So that made it worse I guess.

 

Thanks Graham, I appreciate that!

 

I think I found a workaround, but you probably wont like it.

I use an old version of AutoCad r14 from 1997.
It wont run on Win7 64bit, so I installed a Virtual Machine and installed XPMode.
I've been using AutoCad this way since 2009.

A browser running in a virtual machine will connect to the internet while U5 is running.
I was getting some slow loading times, but its hard to tell if it was just the internet or U5.
Hitting the link again generally loaded fine after a few tries.
I have only tried this for a few minutes, so if it breaks after a while I wont know yet.

You can put XPMode into a windowed state, with the browser window inside that.
So you can use it just like a regular browser window.

Installing a Virtual Machine in Win7 requires Pro or higher, the Home version wont work.
In 2009 the upgrade to Pro cost around $90. The VM and XPMode were free downloads.
Lots of reading is ahead if you go this route, but once its set up its no big deal.
I have 6gig memory and have no problems running XPMode, AutoCad, Photoshop, Lightwave at the same time.

There is a link in the first paragraph to download things.

 

So clicking a link might work just fine.
When it doesnt wait 2 seconds and click again.
When a page with the correct URL appears, and its blank, click reload up to 20 to 30 times.
Get your page.
See how easy that is

 

So I took a chance and bought a brand new usb ethernet adapter in the hopes that it's drivers can handle whatever the Unity 5 editor is doing and keep my internet connection from failing. I purchased the j5 Create usb ethernet adapter (Model: JUE130), simply installed the drivers that came with the packed CD and it's been working fine for over a week now. Not once has the internet connection failed while working with Unity 5. Hope this helps someone. Please note that I'm using Vista 64bit, so I can't really vouch for any other OS. Until this issue is truly fixed, perhaps we could use this thread to start listing ethernet adapters that play nice with Unity 5?

 

Not sure if you have seen this thread.

Unity 5.1 might solve this issue.
First half of June release.

Thanks for the tip.
If 5.1 doesn't fix this, that looks like an inexpensive fix.

 

I found a fix for my machine, see post near bottom.

How about a manual tool to download packages from Unity Store? People select the unity version they have , 5.3.4 , and get the assets.

Named : Manual Assets tool ?

"...I stopped posting here because I cannot make out a pattern. And as long as I can't pinpoint it any further it's no use complaining. Unity know about it but without a definitive cause they can't do anything, either except maybe stumble upon it by chance, it seems. @Rene Damm already said that they don't know exaclty where the problems arise from, either. So unless we all find a common thing I guess this might remain an unsolved problem for some time..."

I ve disabled all network adapters like Hamachi and VirtualBox Host-Only Network and everything foes fine.

 

Hi,
Here is my fix :

Open Cmd with admin permissions and run this command:
> netstat -a -o -n | find "54999"

This will show the id of the proccess let's say it shows :

>> TCP 0.0.0.0:54999 0.0.0.0:0 LISTENING 14824

Just write :
> taskkill /F /PID 14824

To make sure everything is clean, you can run things manually before opening unity. :

> adb forward --remove-all
> adb -s "4f0c7edb" forward "tcp:54999" "localabstract:Unity-com.maincharacter.test"
I hope this helps someone.
Thanks;
