wp-admin not responding…HELP!!!

Ok so my website, https://www.bzhd.zxq.net/ is up, but now here’s the problem. when i try to get into the wp-admin, safari just says:
“Safari cannot open page https://www.bzhd.zxq.net/wp-admin/ because the server unexpectedly dropped the connection. This is sometimes when the server is busy. Wait a few minutes and try again.”
So I keep trying and that same notice keeps popping up. HELP!!!
