Recurring 502 Bad Gateway issue


Hoping one of you out there can offer suggestions or at least tell me I’m not alone. Our WP site has had a random 502 Bad Gateway problem for few days now – happens once every few page loads. I’ve been down the server-side troubleshooting list (with help of Bluehost) and the my-side list (disabling all plugins, updating theme, latest PHP..) – everything on the site is up to date, and 2 bad plug-ins were removed.

Some online articles tell me if this happens once every few loads it’s a server-side problem. The hosting company assures me it is a problem with the ‘optimization of website or database’ – whatever that great expanse of possibilities entails.

I’m running out of questions to ask – I just want my site to load each time somebody visits. Can anybody help?
