Permission problems

I was playing Heroes of the storm with a few friends when I got a short lag on my end that ended up kicking me out of the group I was in. When I tried to join back, all I got was insufficient client permissions (failed on i_channel_join_power). My friends were still in the group, but when they left it to join one I made, they got the same thing, and then they couldn't even get into one together. We were on the teamspeak public test server, so I'm not sure what I can do
