I’m trying to use TeamViewer (full version) but it appears to be blocked by our corporate firewall. Inbound and outbound connections are failing, and I’m getting error code [e.g., 2075 / 2077] . Subject: Firewall blocking TeamViewer – unable to connect

TeamViewer is currently non-functional due to firewall restrictions. Both incoming and outgoing connections time out.
