Connection Blocked After Timeout: Resolving Issues with TeamViewer Free

When using TeamViewer, a popular remote desktop software, some users may encounter issues where their connection is blocked after a timeout. This problem typically occurs when the Cisco Web Security Appliance (WSA) is configured to use authentication and the TeamViewer application is unable to provide domain credentials.

The WSA, a powerful web security solution, aims to protect networks from malicious threats by enforcing strict security policies. However, this can sometimes lead to issues with applications that do not support authentication, such as TeamViewer.

To resolve this problem, it's essential to understand how the WSA works and what settings need to be adjusted. In explicit mode, where a PAC file or browser proxy settings are used, ensure that the 'Apply same surrogate settings to explicit forward requests' option is checked. This will allow the WSA to apply the correct surrogates for the TeamViewer connection.

Another important setting is the Surrogate Timeout, which determines how long the client's credentials are cached. By default, this value is set to one hour, but it can be adjusted based on your organization's security requirements.

If you're using Cookies as surrogates in Identities (GUI > Web Security Manager > Identities), you may need to exclude TeamViewer from authentication. This is because the TeamViewer Agent does not support authentication and may time out when attempting to connect. The access logs will show entries containing 401 or 407 errors, indicating 'Proxy Authentication Required.'

To resolve this issue, disable authentication for TeamViewer by configuring an exemption in the WSA. This will allow the TeamViewer connection to bypass authentication and establish a successful connection.

In conclusion, resolving the issue of a blocked connection after timeout with TeamViewer free requires understanding how the Cisco Web Security Appliance works and adjusting the correct settings. By disabling authentication for TeamViewer and ensuring that the surrogates are applied correctly, you can ensure a seamless and secure remote desktop experience.
