3 of our domains that use for blog the Automad have almost the same issue. At 5-11pm Toronto time they create a 502 Gateway Nginx. We are experience a severe downtime that can damage revenues.
We tried the hosting support and tweaking the nginx preferences (not the nginx.conf) with no success. We have even transfer the DNS to Cloudflare to see if there is a solution.
Now, our other domains that do not use Automad have no issue whatsoever. This is getting more serious by the day. Please, can you provide any suggestions, thoughts or ideas?
