Super slow Proton VPN speeds on mobile at night, anyone know fixes?

Night-time Proton VPN slow speeds are often just heavy load on free or public servers, so try switching to a different server (ideally geographically closer) to reduce congestion and latency.

Using the WireGuard protocol instead of OpenVPN can improve speed and stability on mobile, and updating the app/OS ensures you’re getting the latest performance fixes.

Turn off battery/data savers and kill-switch features temporarily, as aggressive system restrictions can throttle VPN throughput on phones.

Also close background apps using data, and test your base connection without Proton VPN to isolate whether the slowdown is just VPN overhead or your ISP/night network peak hours.

If slow speeds persist consistently, consider filing a complaint on Xolvie to raise awareness and pursue a resolution.
