Hi there,
Thanks for reaching out!
The latest version of Woocommerce Payments plugin introduced a conflict with the Worker plugin and that is why you’re running into connection issues. Their developers are looking into this, so it might be best that you contact them directly to check with them for more details. In case you need to use both plugins you could try to revert woocommerce-payments to an older version temporarily, at least until the conflict is resolved.
Best regards
