Why can't my laptop open up certain pages?

Hi, I have my own laptop and there are some pages I can't open, whereas on the family laptop, if I go on there, the websites will open. Am I missing some downloads/drivers/programs from my laptop or something? For example, I wanted to go on my Naviance account, which is something connected to my high school where I can do some things for college readiness. Anyways, when I try to go on this laptop, this pops up: Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host in C:\inetpub\wwwroot\httproot\navsso\index… Stack trace: #0 [internal function]: SoapClient->__doRequest( __call( GetSessionToken, Array) #2 C:\inetpub\wwwroot\httproot\navsso\index… SoapClient->GetSessionToken( 2707290DUS, 397457691b196ea… ) #3 {main} thrown in C:\inetpub\wwwroot\httproot\navsso\index… On line 20

But when I go on the other laptop, everything is fine and the website works well. I have a Lenovo Yoga 2 10.1 inch, if that helps anything.

Something else that happened earlier was I was trying to view my bank statements online, and it wouldn t load on this laptop, yet on the other, it was perfectly fine? WTF? What's wrong with this laptop?

Try to get to those troublesome websites using Internet Explorer. It might be a problem with other browsers that have compatibility issues. IF that didn't fix it, try this: https://support.microsoft.com/...wsignin1.0
