[Backxtar]

`com.github.theholywaffle.teamspeak3.api.exception.TS3CommandFailedException: A "clientinfo" command returned with a server error.

This is the code:

@Override
            public void onClientJoin(ClientJoinEvent clientJoinEvent) {
                try {
                    ClientInfo clientInfo = api.getClientInfo(clientJoinEvent.getClientId());
                    if (clientInfo.isServerQueryClient()) return;
                    Utils.changeInfo();
                    OnClientJoin.sendWelcome(clientJoinEvent);
                    OnClientJoin.gw2ApiReminder(clientJoinEvent);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }

why does this throws exceptions??

I recall having a similar issue; try using clientJoinEvent.getInvokerId() instead.
