Applies To: The Bosch B426 and the Bosch D7412GV4 panels

Issues: Connection issues occur when configuring a Bosch B426 device to allow communication with the Bosch D7412GV4 panel.

Summary: When configuring the B426 Ethernet Communicator with TLS encryption enabled on the Bosch B426 panel, a connection error occurs. This can be resolved by going disabling the Web and Automation Security option in the panel settings. If the Web and Automation Security option is enabled, failure to establish a TLS session will cause a communication error. The B426 panel will need to be reset after disabling the security option.
