try a different server

We occasionally need to take servers offline for maintenance, during which time you won’t be able to connect to the server. To resolve this issue, simply connect to another server. 

If for some reason you really want to connect to a particular server, the chances are that it will come online again soon. In this case, you can simply wait until it becomes available. Please be aware, though, that we do sometimes retire individual servers for various technical reasons. If this happens, you’ll need to select a different server.  

Try a different VPN protocol

A VPN protocol is a set of rules and procedures that determines how your data is transmitted and secured over a VPN connection. It’s the technology that VPN services such as Proton VPN use to ensure that you have a secure and efficient connection to the internet. Different protocols vary in terms of the security level they offer, their speed, and stability across various network conditions.

If you ca n’t connect using one VPN protocol , try using another . Our Stealth protocol is be can be particularly effective if someone ( such as your isp , government , college , or workplace ) is actively try to block vpn connection .  

Alternatively, our Smart protocol feature will automatically switch between VPN protocols to find one that works best for you.
