504 Gateway Error

Hi, I’m currently testing this plugin to determine if I shoud commit to the PRO version.

Last night a 504 Gateway error occured on my site around 2AM AEST, which is when the plugin was set to backup. Given this, I’m not confident this is the right solution for us currently, but I’d like to see if this is something that can be resolved. Can you help clarify why this happened? The site is running on it’s own Vultr cloud compute instance with 1 vCore, 1024 MB ram, & 25 GB SSD (VPS). I’ve checked the log files and debug information, but they weren’t particularly enlightening to me (I’ve provided them at the end of this message for your reference).

Thank you for your assistance
