You can try resetting the link or reproduce the website.
@raulmego Thanks for getting in touch.
This message can occur if there is something blocking access to the Site Kit service. This could be at host or browser level. So we can determine more on this, please share the following:
- Your Site Health information. You can use this form to share privately if preferred.
- Do you see any warnings or errors when checking yourSite Health status (Tools > Site Health > Status), which differs from your Site Health information requested above? Such errors may include REST endpoint references.
- Have you been able to set up Site Kit on this site previously, or on any other sites on the same hosting platform?
Let me know if you have any questions with the above.
As we didn’t receive a response I’ll mark this as resolved. Feel free to open a new support topic if you continue to encounter issues, or reopen this topic and we’d be happy to assist.
