Try going into your "Settings" and then "WiFi". Next you want to go into the "WiFi's Settings" and then into "Network Config".
The order of these options may be different depending on the type of phone you have, however no matter the route you want to get into the WiFi's network configuration settings.
Once in there you want to access the "Proxy Settings" and make sure they are set to "None".
If the phone's are set to none, and you still have the problem, then you need to check in Chrome's settings.
