Why can't I post a link in zoom chat?

I help with a regular zoom meeting.   I also update Zoom every week.   I use Windows 11 with a desktop computer.  My task at meetings is to post links in chat, which I usually do without any problems.   There is however one link I am unable to post, although the facilitator of the group has done so without problems.   I've also copied and pasted the link into a fresh document, just to see if the problem was with the formatting on my document of links - but it was fine.   Time and time again in chat, the heading for the link posts fine, but the actual link won't post at all.   The second line remains blank.
