Hey there, @Janouras! Thanks for reaching out! 😊
I double checked and can see you were able to chat with my friends in support, which is perfect. I wanted to pop their response below in case it’s helpful:
It looks like the cause lies with your server performance and WooCommerce. I've tested the connection with your WooCommerce account, and it was successful.
Taking a look at the WooCommerce Zapier integration site, they list this error code under their REST API Issues category, and they go on to link to this guide on "Getting started with REST APIs" which contains some useful information on how to set up your store, including working through some common errors.
I'd highly recommend looking through those guides linked above, and if you're still not able to get this connection working, I'd reach out directly to the WooCommerce team for assistance.
You can reach them here: https://woocommerce.com/contact-us/
They did include the log in the email, which may be helpful to share with WooCommerce!
I hope this helps - please continue to keep us posted on your progress with this!
