Using v1.4.3 contentment plugin in umbraco v8.6.3

Everything working fine in non load balancer server but not worked in my live load balancer server. I have a redirection rule in cms server

> <rule name="Redirect To Main" enabled="true">
>           <match url=".*"/>
>           <conditions logicalGrouping="MatchAll">          
>             <add input="{R:0}" pattern="^umbraco/?" ignoreCase="true" negate="true"/>            
>             <add input="{R:0}" pattern="^App_Plugins/?" ignoreCase="true" negate="true"/>
