MAMP not connecting to localhost

Just updated MAMP to version 3.2.1 on Yosemite. Both Apache and MySQL servers are green but when I go to my localhost I keep getting: This webpage is not available ERR_NAME_NOT_RESOLVED in browser (Chrome). I’ve tried incognito browsing and Firefox with the same result, tried both the MAMP default port settings and ports 80 & 3306, tried a reinstall of MAMP and rolling back to previous install of MAMP; all without success.

Can anyone suggest how to fix this…it’s starting to drive me crazy!
