Connection issues

Hi, I'm having trouble connecting to our devices remotely. There seems to be a sytem or firewall issue

It sounds like the devices might not be reaching the TeamViewer servers properly. When this happens, it’s usually a firewall or network rule blocking the connection.

A few quick things to check:

• Make sure the device can access the internet normally.
• Restart TeamViewer on both sides.
• Check if your firewall or security software is blocking TeamViewer’s ports (TCP 5938 is the main one).
• If you’re on a company network, confirm that TeamViewer isn’t being restricted by a proxy or new policy.

Most of the time, once the firewall allows TeamViewer traffic again, the connection works right away.
