Yii Framework website not working on my network

Yii Framework website not working on my network

yii framework website is not working on my office network. When ever I try
to access the website I get "The connection was reset error". I have
checked if the yii website is down using isitdownrightnow.com and it shows
that website is up and running. I talked to my networking team and they
said the website is not blocked by our firewalls. Can you please tell me
what might be the cause of this issue.
FYI : I checked and the website works fine on my home internet connection.
Thanks for your time.
