Hello which server is not working for you? I just tested them all and they work fine...

Hi Sandman77! I can't find your password because it's hashed in database. You can recover your password at https://sandvpn.com/en/forgot. If you still can't connect, contact me at sandvpn@sandvpn.com or via telegram https://t.me/balthSandVPN

Hi Maxim! I just tested all my servers and there are no problems. I recommend you to disable your other VPN extensions and try again. It's possible that another extension is already managing the network settings of your firefox, which may explain the problems connecting to other VPNs. If you still have the problem contact me at sandvpn@sandvpn.com
