Host has blocked meeting

[Sonja28]

Yesterday, two participants were unable to join my meeting. They received an error message saying “Host has blocked access”. For 25 others, this message did not appear and they were able to join without any problems.
All participants are from the same country.

What could be the problem here?

I am not aware of any message that says “Host has blocked access”. However, it is possible that the host may have LOCKED the meeting accidentally, especially if these two participants were last to join.
