Till yesterday it was working fine and everything is OK.
I just restarted the server and started the SAP instance.
All the message server,dispatcher are showing green color and all the WorkProcess are also in Wait stage.
Now,in internet explorer,when i give the url-http://hostname:portnumber,it has to display the SAP Netweaver,SAP Web Application Server Home page.
But it is giving as "the page cannot be displayed".
Previously,i am able to view that.Now,i am unable connect to SDM,Visual Composer,even the Portal page is also not displaying.Earlier it is working fine and able to do all type of configurations in Portal.
