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.
- Make sure you enabled permalinks under the custom structure area. See the example below.
- Wordfence Firewall: Contact Kosmos support and add the eSync assigned IP under Firewall -> Manage Firewall -> Allowlisted IP addresses that bypass all rules.
- Deactivate all of your security plug-ins and test. There are also known connecting problems with iThemes Security. Deactivate this plug-in white list of our Kosmos IPs and test a product sync after. If it fails, I suggest using a different plug-in like WordFence and white list our IP addresses.
- Try deactivating all plug-ins except for WooCommerce. Then test to see if your connection is successful and add one plug-in at a time to locate the culbrit.
- Apache Servers – See the discussion board and check your WooCommerce .htaccess file.
- NGNIX Servers – See the discussion board and review Nginx server blocks.
- 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.
- GoDaddy Hosted WordPress is not supported. You will need to upgrade to GoDaddy Linux cPanel Hosting.
- Returning HTML instead of JSON when testing with Postman? Make sure permalinks are enabled.
