today i was trying to login to my account at miningpoolhub.com
but i got this error: "Unable to login. Please check your email and password.

(Account may be locked if you try login several times with wrong password. Please check your email for instructions to unlock if you think it's locked.)"

I tried a few times, but I got nothing in my email. I also checked my email spam folder. I didn't find anything. Same if I use the "Forgot password" feature, although I know my password.
How can I recover the account? I am mining  and https://miningpoolhubstats.com shows the correct data.
