More downtime, what is the problem now?
You have probably faced the 504 error message quite a few times lately.
And you are probably wondering why since the site got a huge upgrade to address the downtime problem.
Indeed, for sometime the downtime was no longer a problem. But there was a small technical issue that forced me to change how the site works (changing from SPA to SSR, for those who understands this), and that was when the downtime started again.
Some queries are just taking too long to return results, so requests start to pile up until it reach the limit. The server then freezes and eventually restarts itself. That is when you see "Error 504 Gateway time-out".
I having been working on this. I won't be making promises when this will be fixed, but hopefully soon.
