# 5. Error when I try to complete Tasks. What to do?

The error you are experiencing may be due to the use of a VPN on your device. We strongly recommend that you immediately verify if this is the case and disable your VPN to determine if it resolves the issue. 

Additionally, we would like to bring to your attention that using a VPN while accessing the Task Wall on our platform may result in certain Task Providers viewing this as a violation of their policies and terms of service. This could lead to you being banned from accessing their tasks. Therefore, **we advise caution when using VPNs on our platform** and **encourage you to strictly adhere to our guidelines and policies to avoid any potential negative consequences**. 

Finally, the issue may be due to a problem on the Task Provider's end, so **be sure to contact them for further assistance.** You may see how to contact the necessary Task Provider [<mark style="color:green;">here</mark>](/rollercoin/f.a.q./task-wall/8.-how-to-contact-the-task-provider.md).
