Inability to view my flask application on the web

I have been working on a flask application and it has been working just fine. however, for a couple of hours now, i have not been able to run my application on the web. After running the script on command line as usual, i would copy the ip address to my browser in order to display its content but will not respond anymore. I have tried changing port, and other troubleshooting i suppose should work but has still not been able to get it fixed. Any assistance is highly appreciated. The error message is " this site can not be reached" when is actually running on the server in command line.
