Hi,
We are currently using a symmetric key to authenticate the devices and these devices are working fine but today at one of the devices we get the following exception:
Failed to connect: System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
Afterward, the connection was lost, and when we tried to re-connect it prompted for a new certificate after which we were able to re-connect.
Any idea what can be the reason for it and how can we avoid it in the future?
Regards,
Ali Qureshi
