Link that used to work doesnt work all of a sudden for me, but for others it still works

I have a basic account. I am in a group with regular meetings several times a week. Today it just didn't work but I asked others and it worked for them. I have tried to;

* restart the phone

*log out and in again several times

*uninstall and reinstall zoom

*created a new account

*logged in via a friends account

Nothing of the above works! 

I host meetings in this group via that friends account and then I join the other meetings via my own account. It has always worked before. Since March!

I just get this message when I press the link. See attached screenshot. 

What can I do?
