Firefox built-in VPN stopped working after working fine for 10-20 hours, showing "VPN is unavailable - local laws and restrictions" error even though I haven't used up my 50GB limit.

Hello, Until about 10-20 hours ago, the Firefox built-in VPN was working fine for me. Suddenly it stopped working and I can no longer enable it. I have not used up my 50GB monthly limit. When I try to turn the VPN on, after a few seconds I get this error: VPN is unavailable Local laws and restrictions limits where you can use VPN Also, when I check about:config → browser.ipProtection.enabled, I see this response: {"subscribed":false,"uid":5956457,"maxBytes":"53687091200","limited_bandwidth":true} Could you please check why the VPN became unavailable even though my data limit is not exhausted? Thank you.
