Material theme is not working properly when using load balancer

Hi Team,

We have installed material theme plugin in our jenkins instances. When we use the direct hostname like snt900.org.com, the color theme is working fine. 
But when we use to access with the F5 name like Production.org.com the color theme is not working.

Could someone please help me with this issue?

Thanks,
Subash
