Troubleshooting WooCommerce Connection Problems

WooCommerce REST API Connection problems - Unable to Connect WooCommerce

If you’re having difficulty connecting your WooCommerce web store or syncing products/orders please review the below suggestions.

1. Deactivate all of your security plug-ins and test. There are also known connecting problems with iThemes Security. Deactivate this plug-in and white list our Kosmos IP’s and test a product sync after. If it still fails, I suggest using a different plug-in like WordFence and white list our IP addresses.
   
2. Try deactivating all plug-ins except for WooCommerce. For example, the ‘Roles and Rules’ plug-in, is known to cause connectivity problems.
3. Apache Servers - See discussion board and check your WooCommerce .htaccess file
4. NGNIX Servers - See discussion board and review Nginx server blocks.
5. Do you have Wordfence? Contact Kosmos Support (ask for your server ip addresses) and see Wordfence tutorial on how to whitelist your eSync server ip’s.
6. GoDaddy Hosted WordPress is not supported. You will need to upgrade to GoDaddy Linux cPanel Hosting.
7. Returning HTML instead of JSON when testing with Postman? Make sure permalinks are enabled.
