Error 520 - I've tried everything

I have a hobby-only site (I don’t earn money with this) and since the 27th of July the site was unstable and showing error 520. I’ve already consulted my provider and it’s not with them… I don’t know what else to do.
My site is with the latest Wordpress and php too.
I thank you in advance
