Adam,  I can confirm this also happens to me on your link and also some other projects.  Was thinking i may know the problem.  When you join Telegram, you can use it and you have a login name but you don't yet have a global username yet.  I had to go in my telegram settings and "create a username."

I just had to do this recently as someone was trying to manually add me to their group and could not until i did, even though i thought i already had a username.

Was thinking this is maybe why some groups give that error when people try to join them.  If this works please inform me as i would like to know and also inform some other projects where i have encountered this error.

thanks
