If you experience issues connecting or staying connected to any of our servers, you might want to try using a different port to connect to or a different protocol altogether. 

There are multiple reasons why this could be happening:

• You are using UDP (default) behind one or multiple NAT routers that don't support hole punching;
• You are connecting from a public network (such as a school, library, mall, coffee shop, hotel, etc) or a corporate network that filters or restricts Internet usage (typically to prevent abuse and piracy);
• Your Internet Service Provider (ISP) filters some traffic for filtering, quality of service, or restrictive measures.
  Your ISP is actively blocking or trying to restrict the usage of VPN services due to national bans.
• A firewall device on your network is blocking the connection.
• You are using a mobile network with frequently changing IP addresses or service restrictions.
• Your connection is not reliable enough to maintain an active connection for extended periods of time (such as unstable/crowded WiFi access).

In these situations, using a different port or protocol to masquerade as another kind of application typically resolves the issue.  For instructions on how to change the ports on our application, please review the following guides:
