Troubleshooting IIS (Net Information Services)

Concluding modified: March 15, 2022

1 Introduction

This folio volition assist y'all troubleshoot issues you come across when setting up Microsoft Internet Information Services (IIS) as a webserver in front of Mendix.

It is broken into iii sections:

• Troubleshooting the Mendix Installation
• Troubleshooting IIS
• Troubleshooting Mendix Service Console Errors

two Troubleshooting the Mendix Installation

Firstly, make certain that your Mendix app is working before looking for issues in your IIS configuration.

2.ane Bypassing IIS to Run Your Mendix App

When you lot open the application normally it will attempt to access it via IIS. To test Mendix without IIS, y'all demand to admission it directly.

Open up the browser on your server and go to the app at http://localhost:8080/ (or the port that y'all have configured, if unlike). If the app is working you lot will find it here.

If the app is working, then the issue is with your IIS configuration.

If there are problems with the Mendix app you should see error letters in the Mendix Service Console and/or in the browser.

2.ii Disquisitional Files Not Constitute

Y'all can get this sort of error in 2 circumstances:

1. The files are missing, or in the wrong place

   Search for the correct platform version, and the file referred to in the error bulletin.

   If the files are missing, you lot should re-install the server distribution (tar.gz file) and confirm that the files are now in the correct identify.

2. The Mendix service cannot access the files

   If the files are at that place, ensure that the user running the Mendix service has read and execute access to the mxclientsystem folder.

three Troubleshooting IIS

This section describes a few common problems that people have run across when setting up IIS.

We cannot provide a solution here for all the problems you may notice. Use the techniques below to isolate the crusade of your problem. If the solution is not clear, at that place are many resources on the internet which tin help you to solve your specific issue.

Y'all can also enquire for help on the Mendix Forum.

If you have some useful tips, please feel gratis to add them to this certificate.

iii.1 IIS Access Permission Error

When opening the website in the browser, an IIS mistake page regarding access permission is displayed.

Validate your security settings. The user that runs the IIS service must be able to access the full directory path. (This is probably user: IIS_IUSRS, just confirm this in your service list). If your Mendix awarding is installed on "E:\Mendix\projects\MyApp" the IIS user must be able to read all the folders in the hierarchy (Mendix, projects, MyApp, and the web folder within MyApp).

3.2 Login Procedure Fails: 404 - Server Non Plant

You can meet the login page in the browser, but when triggering an action yous become a 404 or "server not found message".

• Did y'all have to enable or install additional plugins?

  If then, make sure to restart the entire IIS service. You can configure the newly installed settings, but they won't have any effect until you restart the full IIS service.

• Did you add new configuration settings, like the rewrite rule?

  Of course yous did, but did you likewise restart the website? After adding new configuration options like the rewrite URL y'all need to restart the website. Y'all can do this by correct clicking on your newly created site and yous should see a restart pick.

3.3 Wrong Response When Using Invalid Credentials

You can sign in, simply when entering an invalid countersign the login page shows 'server non plant' instead of invalid login.

Some IIS installations hide the content of any response that isn't HTTP condition code 200-OK. If you enter invalid credentials during a Mendix login, Mendix returns a status lawmaking in the 400-range to betoken unauthorized access. This response also contains a JSON cord with the response we want to show to the user.

Mendix cannot piece of work if IIS is hiding detailed mistake letters. You demand to turn on 'Detailed Fault Letters'. The instructions on how to change this setting for your website can be found on the Microsoft website here: IIS7 : HOW TO enable the detailed error messages for the website while browsed from for the customer browsers

3.4 Reviewing the Mendix App Log

First assess whether yous are hit the Mendix application. If IIS frontwards anything to the running Mendix app you can see that in the log. The log nodes 'Connector' and 'Jetty' can exist about helpful. The Connector log node is able to print information about any incoming request. If you enable Trace logging yous can see if the request comes in to the correct asking handler.

If the 'Connector' doesn't impress anything yous can also enable trace logging on 'Jetty'. The 'Jetty' log node will impress a message for every connectedness that is established with Mendix. If Jetty doesn't print a trace bulletin the IIS rewrite rules are definitely not setup correctly.

If yous exercise have data in the 'Connector' log node yous tin see where the requests are being forwarded to. This should help you lot sympathise where the rewrite rules are directing traffic and how to change it.

3.5 Reviewing the IIS Log

If you conclude that no messages are arriving at Mendix, you tin enable IIS trace logging. This prints every rewrite dominion to an IIS trace log file; you can see exactly how IIS changes the request and where it is forwarded to. This should provide you with the information needed to right the configuration of the rewrite rules. Run into this Microsoft page for more information: Using Failed Request Tracing to Trace Rewrite Rules.

3.6 Using Browser Developer Tools

Open the awarding and audit the requests with your browser's developers tools. If the awarding isn't working yous volition see requests that are not successfully executed. Examine these requests to encounter if at that place is a design.

1. All the /xas/ requests fail with an error.

   The rewrite is probably incorrectly configured. Open the /xas/ folder in the browser. You may then be presented with a more detailed caption about the cause of your problem.

2. Some JavaScript files cannot be opened.

   Endeavor opening the files directly from your browser. If there is an result in your IIS configuration y'all volition get more than data when opening that URL.

   If y'all still receive the mistake, it is most likely a security trouble. The user under which your website is executed does not accept sufficient privileges to access the required files.

4 Troubleshooting Mendix Service Console Errors

4.1 Security Errors While Starting Service

When the system gives security errors while starting the service, make sure that the configured service user has sufficient rights to the folders of the Mendix application. Sometimes you have to prefix the user name with the domain proper noun; that is, apply DOMAIN_NAME\user_name instead of just user_name.

iv.2 Blazon Initialization

Sometimes the Outcome Viewer shows a message like this:

              EventType clr20r3, P1 mendixservice.exe, P2 1.0.3810.25652, P3 4c0cf0d8, P4 mendixservice, P5 ane.0.3810.25652, P6 4c0cf0d8, P7 two, P8 6, P9 system.typeinitialization, P10 Nada.                          

Make certain that the user account used to run the service has enough rights to the folders containing the Mendix Service executables.
