I am not able to log in to the teamspeak application, there is always a failure and I get the message that you can see in the image https://i.imgur.com/zqCUjQu.png... this has been happening a long time since the last upgrade. this error only happens in version 3.2.3, when I download an earlier version of teamspeak I can log in without problems. many friends of mine are also with this problem ... I do not know if it is a problem of region because I am located in Brazil, can someone explain to me what is happening?

ps.Sorry for the quality of the text, I used google translate.
