Hello Rafael,
Thank you for your message.
Could you please clarify what type of connection do you use? If your Host and the Viewer are on the same LAN or VPN and you use a
direct connection, please refer to this troubleshooting guide:

Internet-ID connection, solutions listed in this article might be helpful:

Please note, that version mismatch between Viewer and Host/Agent may lead to performance issues and some features not working. Also, if you use the self-hosted server (RU Server) update it to the most recent version too.
The latest version is 6.10.9.0 and it's available for download
here.
Hope that helps.
