Welcome Group link not woring

Hi,

I saw a similar error someone had posted awhile back with the error saying, "Your request couldn't be completed. Please try again. If the problem continues, contact your email admin." when clicking on the welcome email to join a group but I couldn't find a solution that fit what I would need to do. I shared a screenshot and covered the name of the group (for privacy reason). Is this a result of an invalid link? I am not sure what I would need to do to resolve the issue.
