Thanks in advance. Subject: Firewall blocking TeamViewer – unable to connect to remote devices
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] . teamviewer blocked by firewall
Unable to provide remote support to external clients / internal users working from home. Thanks in advance

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