Like any route, congestion can slow what should be a fast connection to a halt. When you connect to CactusVPN you have to go through your ISP, which then connects you to us. If it happens to take a route that is either very busy or very long it means your connection will be slow. This can happen anywhere along the route although we monitor our network 24 hours a day to ensure we are not the cause.
Speedtest.net is a great service, but it’s not always appropriate for testing your VPN connection speed. Their results depends on many factors because anyone can add his server as a test server and it’s speed could be even lower than your speed. The best way to test your real download speed is to download a popular torrent while being connected to our VPN.
1723 and 443 TCP ports should be open, also your firewall / router / ISP must allow VPN / PPTP pass-through.
Typical working: embedded Microsoft firewall in Windows, Linksys/D-Link/TP-Link/ASUA Router manufactured after year 2007, ADSL broadband.
Typical not-working: not-Microsoft firewall, Netgear/Trend Router, all router-integrated ADSL modem. If you get error 619 with ADSL connection, please remove home router and disable not-Microsoft firewall software.
OpenVPN uses strong encryption and it is normal to experience slower connections. If you are not highly concerned with your privacy we advise you to use PPTP or L2TP/IPsec connections.
We have had to block certain ports (22 and 25) as some clients were abusing our service. This reduces abuse reports by 100 times which means we'll have more time to make your experience better!
Seems that you use the SMTP for outgoing mail transport, which uses TCP port 25. Many spammers try to profit VPN services for transmitting spam. That's why we blocked the 25 destination port while using our services.

If your provider supports IPv6 there is a chance that regardless if you are using VPN or not the sites will detect your IP address by your IPv6. In order to avoid that please disable IPv6 from your device.
There are may be two possible reasons for that:
Some antiviruses might find our app suspicious. This is usually happening on the first days after an update because some antiviruses build their databases using the number of installs of specific apps. Let’s say our app is installed on less than 20 computers with a specific antivirus. In this case, this antivirus can mark our app as suspicious. It will be marked back as trusted when it will be installed on more computers. So don’t worry, your PC is safe!
