VPN won't connect

Have not had this problem before but my MacBook Air cannot connect to the server today… have tried numerous times? I read some things about what to try but they only seem to address this as a standalone product saying that if it’s through the Avast Anti-Virus it is installed automatically so the instructions to uninstall and reinstall don’t work. Is there something wrong with the server? What can I do to try to fix this. It keeps trying to connect but has not been successful for several hours. Thanks for any advice.

This is being solved with Sally via email.
