This can happen sometimes when you are using free version of VPN.
You can try changing your IP address location, but I would suggest switching to some better VPN services.
Mullvad is number one, but it is a bit expensive, and good alternative is NYM VPN, that is decentralized and you can pay with bitcoin, monero and other crypto with discount.
PS
I don't trust ProtonVPN, and most VPN's are probably honeypots.
