Unable to access Futures Testnet

There’s a restriction in some way (for example by country) to access the https://testnet.binancefuture.com?
I have Binance account for years and updated recently for verification and tried to switch to mock envinroment, and when I got redirected to the mock page (https://testnet.binancefuture.com) this message error show up: “Can’t find future account id with uid XXXX” and I unable to see the trading form, API key/secret and etc.

I also tried to create a new acocunt, with new email/pass and no verification on the registered email was received. Don’t know why.

So, whats going wrong? New registers are disabled for now? What does “Can’t find future account id with uid XXXX” mean?

I have exactly the same issue
