HTML/CSS Rendering on GeckoWebBrowser local development system and Deployed server - asp.net

Question

I used GeckoWebrowser control in my VB.Net desktop application by following this link .
It is working fine, but the problem is about proper rendering of CSS and HTML. When I navigate browser to local installed IIS application like:
GeckoWebbrowser1.Navigate("Localhost:8081").
The website renders completely and works fine, BUT the same website is not rendering properly when I called it from domain:
GeckoWebbrowser1.Navigate("124.25.54.50:8545").
Please help me how to resolve the problem. I tried every where but failed.
Below is my Code:
.grdarea1
{
float: none;
/*height: 30px;*/
font-size: 16px;
line-height: 0px;
margin: 0 0 0 10px;
padding: 2px 0;
text-transform: uppercase;
text-align :left ;
border-radius: 5px;
