Issues on invitation link

Question:

Hi,
I’m using Replit for teaching purposes. Last week some issues happened when sending invitation to my students. I used the Classroom integration to send them.
Some guys (about 30%) were able to accept the invitation while for the others an error message appears when clicking on the invitation link received on the email. I attached the screenshots of the error messages.
Can someone help me, please?

Kind reagards
