Glossary Entry Page Cannot Be Accessed (server not found)

I created a new glossary but when I am trying to save it, an error message appeared on my screen. I have never experienced this kind of issue even if I am trying to use Question Bank. This error also directs me to the home page of my browsers stating about the three possibilities which I don’t think are related to this issue. Do you have any idea on how to resolve this issue? I can’t think of any resolution on this issue anymore and it bothers me a lot because I cannot access the Glossary Entry page anymore.

Error:

Server  not found

Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer's network
connection.
