What is the issue you’re encountering

Error 520 fica aparecendo de forma intermitente no meu site, tanto no 1º acesso quanto ao paginar site, basta atualizar a pagina pra normalizar, porem fica toda hora aparecendo esse erro.

What steps have you taken to resolve the issue?

Ja desativei temporariamente os caches, limpei tudo, testei o acesso de outras ips/dispositos (somente no celular o erro nao apareceu ao navegar no site) comprei o domnio retroearn74.com na cloudfire, (antes era .com.br comprado em outro site e o erro era o mesmo) e nada adiantou, ajudem por favor
