Microsoft Teams Stuck in Queue

Was having difficulties with a Teams meeting where my coworker could not join the meeting despite him clicking the link to access it. He was placed in a meeting queue where he was told to wait to be allowed in despite it allowing other users in without having to be approved by the meeting host/admin. The host could also not see him waiting in the queue despite knowing he was stuck in the queue and could not join. We tried connecting from his phone and computer and even restarting his computer or trying to join as a guest to no avail. We even tried having the host leave the meeting and reconnect as well as starting up a whole new meeting. He could join other meetings just fine but could not get past the queue lobby for this group meeting.
