errors in loading in web and panel

In the month of February I migrated my pages in wordpress to be used with the panel, with the help of iraquiboy, the pages were functional and working perfectly. For three months it worked perfectly. Since the end of May not only my pages but also the panel goes very badly, I check the logs of nginx, varnish, apache, the same panel but there is no error that helps me, I just get these graphical errors, loading errors and they come out 520 .... please help?
