I am trying to install some dependencies on my Eclipse Oxygen when I suddenly hit this error. The full error message is: 

Cannot open Eclipse Marketplace

It was fine before. I started to see this error after I installed IBM WebSphere Application Server V8.5x Developer Tools for Oxygen. I am very new to Eclipse so I'm not sure how to debug this.

Yes I have internet and I have no antivirus installed (it's running in a CentOS VM). I also have tried resetting the network connection settings to default but its not working.

Adding marketplace.eclipse.org/catalogs/api* to the Proxy Bypass settings solved this problem

Tried everything possible on the internet! Failed. The issue is with our network only. Please check if you have any content filtering enabled on your network, URL blocker/filter, security-enabled that blocks certain keywords in URLs. For me, It was Content Filtering enabled on my WiFi Router, which was blocking certain URLs.
