WordPress Rest API not working following website migration.

meditatingsurgeon

I migrated a couple of websites to another server in my cluster. I've found on both sites that the WordPress Rest API is not working. I've checked the permalinks to reactivate the Rest API to no avail. I've tried rebooting as well as reinstalling from a working backup but still no connectivity. I've even tried migrating one of the sites to the original server but no good.
Has anyone else encountered this issue and is there a workaround.

We too have faced this issue recently.

If you are using cpfence wp security then yes.

cPFence doesn’t block the WordPress REST API. You can test it using:

https://cpfence.app/wp-json/
https://cpfence.app/wp-json/wp/v2/posts

If those load fine on your end, your issue likely lies elsewhere.

Just make sure your server IPs are whitelisted as explained here.

If you still run into issues, feel free to open a ticket and we’ll be happy to take a look.

I'm not versed in cPFence but that could be the issue.

If you manually go to: domain.com/wp-json/wp/v2/users does anything load? If it doesn't load, something is blocking it.

i had a case where PATCH was not working, when sent from a website i hosted to a 3rd party, ip whitelist did not work,
apparently i had enabled one of your wordpress hardening things, once i disabled , everything worked.

cPFence i am not saying it in a bad way, i like your product.

Thanks! Feel free to drop us a ticket anytime, happy to help you get it sorted or fine-tune the hardening rules to fit your setup.

I am now also facing this issue for the second time. To me it appears to be linked to chaning the primary domain. That seems to cause the Rest API to break.

Last time my workaround was to make a backup in wordpress, remove the site from Enhance, create a new site in Enhance, restore the backup in wordpress.

Not sexy, so a fix to the root cause would be appreciated 🙂

Ps. I'm not running cPFence, it is a pure Enhance server.

Edit: SOLVED with Adam's help. It seems changing the domain somehow removed a rewrite in "Developer Tools" > "Nginx" > "Rewrite". Adding back / to index.php resolved the issue.
