The Endpoint Encryption Manager Change Web Access Command fails if the Endpoint Encryption server has TLS 1.0 and TLS 1.1 disabled.
The Change Web Access Command allows you to update Endpoint Encryption clients with new Web Server details, Certificate Data or IIS credentials. The command is located under Endpoint Encryption Managed Computers / Set Server Commands.
When you click OK to update the settings you receive this error:
Symantec Endpoint Encryption 11.3 and above.
Temporarily enable TLS 1.0 and TLS 1.1 by opening SEEMS Configuration Manager, navigating to the Web Server section and turning off this option:
Disable TLS 1.0 and TLS 1.1
You will also need to enter the Web Server password again.
Click Save to save the setting.
Reboot the server for this change to take effect.
After you have successfully run the Change Web Access Command, you can disable TLS 1.0 and TLS 1.1 again.
