WebGL issues on latest Chrome (Uncaught incorrect header check)

Hi all,
I have the error (Uncaught incorrect header check) on Chrome 47.0.2526.80. Firefox and Safari working fine. I am using OSX and Unity 5.3.0.f4

Whats happening?
The UnityLoader.js requesting the WebGL.data twice. The first request looks like the following:

Request #1:

1. Request URL:
   https://**.com/unity/Release/WebGL.data
2. Request Method:
   GET
3. Status Code:
   200 OK

Response #1:

HTTP/1.1 200 OK
Server: nginx/1.4.6 (Ubuntu)
Date: Sat, 12 Dec 2015 09:23:04 GMT
Content-Type: application/octet-stream
Content-Length: 114961309
Last-Modified: Fri, 11 Dec 2015 08:39:27 GMT
Connection: keep-alive
Vary: Accept-Encoding
ETag: "566a8bbf-6da2b9d"
Content-Encoding: gzip​

but the UnityLoader.js LoadCompressedFile.onProgress throws: net::ERR_CONNECTION_RESET so the file loading gets canceled after 11 megabytes loaded (out of 110MB).

which seems to trigger the second request which looks like Request #1

and the Response #2:

HTTP/1.1 200 OK
Server: nginx/1.4.6 (Ubuntu)
Date: Sat, 12 Dec 2015 09:23:15 GMT
Content-Type: application/octet-stream
Content-Length: 114961309
Last-Modified: Fri, 11 Dec 2015 08:39:27 GMT
Connection: keep-alive
Vary: Accept-Encoding
ETag: "566a8bbf-6da2b9d"
Content-Encoding: gzip​

is loading the whole content of 110MB after the is complete the Error gets thrown:
Error: Uncaught incorrect header check

So any ideas? As said I working well with Firefox and Safari.

PS: I am wondering why Unity(Loader.js) renames the requested files (+="gz") which I have defined before in the Module Object (dataUrl,memUrl...) gzip file selection by given request header information is the responsibility of the server and the loader shouldn't do that.

 

May help

I am not using apache and as you can see in the posted Response Header the Content-Type is set. Thank you anyways. Since the problem occurs only at certain chrome versions and other browsers working I don't think the mime type settings lead to a fix.

 

I'm using IIS and getting Uncaught incorrect header check errors too, very little clear information on any of this.

 

Monark , my IIS local works using this web config.

Code (CSharp):

1. <?xml version="1.0" encoding="utf-8"?>
2. <configuration>
3.     <system.webServer>
4.         <staticContent>
5.           <mimeMap fileExtension=".mem" mimeType="application/octet-stream" />
6.           <mimeMap fileExtension=".data" mimeType="application/octet-stream" />
7.           <mimeMap fileExtension=".memgz" mimeType="application/octet-stream" />
8.           <mimeMap fileExtension=".datagz" mimeType="application/octet-stream" />
9.           <mimeMap fileExtension=".unity3dgz" mimeType="application/octet-stream" />
10.           <mimeMap fileExtension=".jsgz" mimeType="application/x-javascript; charset=UTF-8" />
11.         </staticContent>
12.     </system.webServer>
13. </configuration>

Sadly though I can't get webGL working on a server that uses htaccess. Maybe I need to convert this to htaccess some how? I keep getting the Incorrect Header on my web host, but again works great on my IIS.

 

I am also getting this error using IIS

 

Had this issue too its due to the Web.config (tested on IIS on Azure). I created a short video that has the fix in it here ... http://blogs.msdn.com/b/cdndevs/archive/2016/01/05/hosting-unity-webgl-games-on-azure.aspx

This is the web config I used

<configuration>
<system.webServer>
<staticContent>
<remove fileExtension=".mem" />
<mimeMap fileExtension=".mem" mimeType="application/octet-stream" />
<remove fileExtension=".data" />
<mimeMap fileExtension=".data" mimeType="application/octet-stream" />
<remove fileExtension=".memgz" />
<mimeMap fileExtension=".memgz" mimeType="application/octet-stream" />
<remove fileExtension=".datagz" />
<mimeMap fileExtension=".datagz" mimeType="application/octet-stream" />
<remove fileExtension=".unity3dgz" />
<mimeMap fileExtension=".unity3dgz" mimeType="application/octet-stream" />
<remove fileExtension=".jsgz" />
<mimeMap fileExtension=".jsgz" mimeType="application/x-javascript; charset=UTF-8" />
</staticContent>
</system.webServer>
</configuration>

 

Thank you! This works.

 

Thank you very much! It works!

 

ScruffyFurn, your link does't work but I found your article: https://blogs.msdn.microsoft.com/cdndevs/2016/01/05/visual-studio-plug-in-for-unity-linux/

But Web.config there does not exist

 

At a minimum for WebGL games to work under IIS you need to have or add the mime type for application/octet-stream .datagz and application/octet-stream .memgz. This can be done by creating a new site and pointing the path to your WebGL build folder (the one with the index.html), then go to your site in IIS and select the MIME Types feature. The add these 2 types. Browsing to the site should then work. This will create the web.config file in the WebGL root folder as well

 

I use this Web.config in root of my website:

Code (CSharp):

1. <?xml version="1.0"?>
2.  
3. <configuration>
4.  
5.   <system.web>
6.     <compilation debug="false" targetFramework="4.0" />
7.   </system.web>
8.  
9.   <system.webServer>
10.     <staticContent>
11.       <mimeMap fileExtension=".obj" mimeType="application/obj" />
12.       <mimeMap fileExtension=".mtl" mimeType="application/mtl" />
13.       <mimeMap fileExtension=".dds" mimeType="application/dds" />
14.       <mimeMap fileExtension=".fbx" mimeType="application/fbx" />
15.  
16.       <mimeMap fileExtension=".mem" mimeType="application/octet-stream" />
17.       <mimeMap fileExtension=".data" mimeType="application/octet-stream" />
18.       <mimeMap fileExtension=".memgz" mimeType="application/octet-stream" />
19.       <mimeMap fileExtension=".datagz" mimeType="application/octet-stream" />
20.       <mimeMap fileExtension=".unity3dgz" mimeType="application/octet-stream" />
21.       <mimeMap fileExtension=".jsgz" mimeType="application/x-javascript; charset=UTF-8" />
22.     </staticContent>
23.   </system.webServer>
24.  
25. </configuration>
26.  

 

Hello,
I have windows server 2012 r2 with IIS 7. I have tried this but my files are not running. Can you take a look and suggest more on this https://moodle.gaia-tech.com/downloads/maths/.

 

Code (CSharp):

1.   var Module = {
2.     TOTAL_MEMORY: 268435456,
3.     errorhandler: null,            // arguments: err, url, line. This function must return 'true' if the error is handled, otherwise 'false'
4.     compatibilitycheck: null,
5.     dataUrl: "Release/.data",
6.     codeUrl: "Release/.js",
7.     memUrl: "Release/.mem",
8.    
9.   };
10.  

The file name is not present .....

 

Yes but when i use this on my local server all works fine.

 

New issue : UnityLoader.js 404 not found. But i have that file.
