We contacted NeoBux' customer support and they told us to clear our cache and cookies, try changing our browser, and check our proxy, firewall and other security settings. These troubleshooting steps didn't help us at all.
We didn't blame NeoBux for this since yesterday we found out that the problem is on our end. We tried renting on nearby internet cafe and accessed our account from there, and tried clicking ads. It is working. Thus, we concluded the problem was not on the site.
Today, we scanned our computer and had a maintenance. During the process, we decided to visit www.filehippo.com where we want to download something. It was our surprised when we found out that it was not loading, too, like the NeoBux ads. This confirmed our conclusion that the problem is really on our connection.
And what solved our problem?
We just reboot our modem.
Yeah, it's just a simple solution that resolved a problem that we thought complicated at first.
So for those who will be having some internet problems like us, try to have a troubleshooting first.
