I know there are a few posts out there about “503 Backend fetch” errors but I’m no further forward as to what’s causing them and how to resolve them. I’m seeing them on every Wordpress site I host with Cloudways but some sites more than others. One site in particular seems to have more than any other - so much so that Google Search Console is starting to report them. The errors seem to be more prevalent when someone uses a browser back button but there’s nothing consistent about it as far as I can tell?
I have tried various Breeze and Varnish settings, all to no avail and I really need to get this fixed or find an alternative hosting solution.
Thanks in advance for any thoughts or suggestions.
