Getting a bad response message

Hello, I’m having problems with my website all day.
I get the 502 Bad Gateway response one minute and the other the website seems to be working fine.

If someone could take a look, that’d be very appreciated. www.lendocomlucas.xyz

I see that their servers are undergoing some planned maintenance. Could the gateway problem I’m having be related to this maintenance? I’m new to this, so I’m sorry if I’m being, by any means, redundant.

Thanks in advance!
