Thanks for reaching out @rigel88x. Given the “site not found” error you’re reporting, I suspect that what you’re facing may be due to some invalid site records or an invalid callback URL for your site. So we can determine more on this, and ensure you can get Tag Manager connected successfully, please share the following:
- Your Site Health information. You can use this form to share privately if preferred.
- Did you make any site URL changes to your site recently, such as changing your wp-admin path or WordPress files location? If so please share details of any such change.
- At what stage example do you encounter the “site not found” error? By that I mean is this directly after selecting your Google account, or when selecting the option for Site Kit to create a new Tag Manager account?
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.
