Environment

vRealize Automation 7.x

Cause

The issue occurrs when the payload exceeds limits set in the IIS stack

Resolution

1) Snapshot each iaas web server

2) Take a manual backup of the web.config file located C:\Program Files (x86)\VMware\vCAC\Server\Website\web.config

2) On each iaas web server add the maxRequestLength property to the website web config file located under C:\Program Files (x86)\VMware\vCAC\Server\Website\web.config

Add the property maxRequestLength="10240" to the httpRuntime line.

The amended line should look like below with added entry highighted in bold:

<httpRuntime targetFramework="4.5" maxRequestLength="10240" maxQueryStringLength="146384" enable="true" executionTimeout="1000"............

3) Perform iis reset for change to take affect. Open command prompt as administrator and run command:

iisreset

4) Validate you can now see the machines properties in the UI
