Difficulties in connecting to Proton VPN servers

Earlier today, we experienced a congestion issue in Proton VPN's WireGuard authentication layer, which created problems that made it impossible for some users to connect using the Wireguard protocol. After a deeper investigation, the root cause of the congestion was found to be due to a configuration error that was not appropriately updated when the number of Proton VPN users increased. A permanent fix was put in place to prevent a future occurrence of this problem. We apologize for this issue, and will keep working to improve to avoid such issues in the future.

The root cause has now been identified and our team is working on a solution. We apologize for the inconvenience.

We can confirm we've found the issue and are applying a fix within the next few minutes. We appreciate your patience.

We are continuing to investigate this issue.

We are investigating some issues affecting a part of the Proton VPN user-base when connecting to Proton VPN servers. We apologize for the inconvenience and try to resolve the situation as soon as possible.
