503, 504 Timeout Gateway

I have issued with this plugin and DO Spaces.
when DO spaces have an Incident (see: https://status.digitalocean.com/incidents/9qt08grjb64q), my site cannot load properly.
i have disable this plugin, then my site work normally.
when incident from DO is fixed, then i activate plugin. it’s still got 504 Gateway Timeout.
