Can't upload avatar at Teamspeak5

Just like title i can’t upload my avatar at teamspeak5
This prompt pops up every time you upload,the strange thing is that you can see my avatar in the community

I think your ISP (or country) has rules to block our services and that’s a possible reason.
You may find related errors in your client log %LocalAppData%\TeamSpeak\Logs\Default

The avatar shown here and the one in client may be loaded from different internal services.
