The issue might be due to providing the wrong password of source wifi. But since you have tried connecting the Bolt to wifi multiple times, there is a very low probability that you have entered it wrong. Still, make sure that you are entering the correct password.
Bolt doesn't connect to wifi source working on 5Ghz, so make sure that your wifi works on 2.4Ghz frequency. Do try to connect to the mobile hotspot which is not open. Also, connect to Hotspot of some other device apart from the one which you are using for configuration.
