Recently I have been getting a lot of 503 errors. They don't happen in any pattern. The only way to get them to willingly show up is by opening a bunch of orders(20-50) in WooCommerce. But sometimes it just seems to happen very randomly.

I have tried:

• Create a test domain
• Update PHP version
• Disabled a lot of plugins
• Update plugins/wordpress etc
• even tried caching
• Reading the debug file and logs in the root (nothing of use)

But nothing seems to get rid of the random 503 errors. The issue is very annoying when working on our orders but also shows for our customers. Google doesn't have any answer and I simply don't know what I am looking for.
