Sorry to hear that. Unfortunately, some websites block known VPN IP addresses. Contact us at https://protonvpn.com/support/contact with more details about the websites in question and the servers you're connected to when trying to access them so we can note your feedback for future improvement. Meanwhile, try switching between multiple different servers to see how it goes.

On another note, we constantly monitor server loads and our team makes sure to provision additional servers in areas where there's constant high demand.
