Continuing the discussion from 502 Bad Gateway:
Has anyone discovered a solution to persistent 502 Bad Gateways in Kibana? We are running ES and Kibana v 7.4, and have had this problem since starting our cluster in April (1 Kibana node, 3 master ES nodes, 100+ data nodes). These 502s will come in waves, with our users experiencing no 502s, and then for 2 minutes straight, they'll get a white screen that says "502 Bad Gateway."
^We see these ~10 times in an hour.
