Why is there a ### sign in the place of a linked text or graphics?

When our page is an internal link that is published and available only within the organization/company and is not publicly accessible, a situation may occur where after adding the link and saving the hyperlink, a # will appear under the text or graphic.

This system behavior is dictated by system security and pinging the IP of the page to which we want to direct the respondent. In order to properly add a link to internal resources, it must be shortened using services available on the web, e.g.: https://tiny.pl/

We add the shortened link again in the URL field and save.
