I have a similar issue and have had to rollback my wpengine hosted instances to 4.9. It seems the WordPress Address (URL) and Site Address (URL) in General Settings is not working as it previously did (intended or unintended). The description onder Site Address (URL) says

Enter the address here if you want your site home page to be different from your WordPress installation directory.

However, in version 5.*, when you try to update a post (and publishing, maybe some others), it tries to use the Site Address (URL) instead of the WordPress Address (URL).

I saw a different support post that had been resolved, but the moderator’s comments were that the customer was incorrect in setting it up. https://ww.wp.xz.cn/support/topic/updating-failed-wp-5-0-2-when-wordpress-address-differs-from-site-address/

We are trying to leverage a different Site Address (URL) for reverse proxy and ultimately SEO boost. Everything was working fine on 4.*, but stopped working on 5.* If wordpress developers would use the wordpress address (URL) instead of the Site Address (URL) for all functionality within /wp-admin (including ‘wp-json/wp/v2/posts’) it would correct the issue I and some others are having.
