Cannot find password

Our site is built with WordPress. is always redirected to, however I don’t remember how this redirection is set.

I wanted to sign in the dashboard of WordPress, but my username and password did not work anymore (for long time I did not sign in). I tried to find my password, but the following page just hanged.

Does anyone why finding lost password does not work? Is it related to the redirection? Is there other way to sign in?
