Login credtials File Manager are wrong


when I click on my File Mager it shows following message:

The Login Data is 100% right!

Yesterday my website received https://mund-nasen-bedeckung.000webhostapp.com/ 502 Bad Gateway
In my dashboard it shows me following status
It’s green. So why can I not login into my website?
Thank you in advance.
