#2 Modify DNS servers
You may try to change the original DNS servers in your network adapter. To do this, open the "Network and Sharing Center", right-click with the mouse on the active Internet connection and select "Properties", then select "Internet Protocol Version 4 (TCP/IPv4)", click on "Properties", enable the option "Use the following DNS server addresses", now type 18.104.22.168 in "Preferred DNS server" editbox, and 22.214.171.124 in "Alternate DNS server" editbox, finally click on "OK" button.

#3 Reset proxy settings
Is possible that in some cases you cannot access tubecup.com because a web toolbar or a spyware has modified your web browser's proxy settings. So you may try to reset the web browser's proxy and then you may try to access again the website to see if it works fine. Generally the proxy settings are located in the web browser's options page under the section "Advanced" -> "Network" or "Connections" -> "LAN Settings". Make sure to enable the option "No proxy" or however untick the option that uses a proxy.
#4 Try other web proxies
If this web proxy does not work, you may try to use other web proxy servers, for example hidebux.com or cantaccess.com or hidewebsite.com to see if you can access tubecup.com via those new web proxies. If you are still not able to access the website via those other web proxies, then you may need to buy a reliable and fast VPN service, because it means the website does not work correctly via web proxies (you know, they have some limitations).
