Hey there Gerald,
I’m sorry about the delay in getting back to you!
When orders are stuck on pending, that points to an IPN (instant payment notification) issue, where eWay can’t respond back to your site about the status of the payment. Once that IPN has been received, the order status is updated.
This is often caused by a plugin and/or theme conflict, and often turns up after updating which introduces a new conflict.
You were on the right track with Health Check, but it isn’t a good tool when testing payment gateways, as the API level code isn’t affected by Health Check.
The best way to determine if the issue is being caused by a theme and/or plugin is to temporarily switch your theme to Storefront (https://woocommerce.com/products/storefront/) and disable all plugins except for WooCommerce and eWay. Finally, test to see if the issue is resolved by making an order with eWay and seeing what the order status is.
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, continue to the next step.5. Reactivate your other plugins one by one, testing after each, until you find the one causing conflict.
