I want to add an external URL on my google site, and I can add and access URL link in "preview" mode where the format of the link address is https://www.google.com/url?q=myurl
However, when the webpage is published, the link address will become https://sites.google.com/view/username/myurl and cannot be accessed resulting in a 404 error.
Is there a way to solve the problem? Thanks in advance!
Google corrected this issue recently, now it works fine. The question is closed.
