AOS 8.4.0.4 cluster with MM & standby MM
When using Firefox I get a cert error when connecting to one of our MCs. I have added exceptions for the other controllers (some time ago) but for this particular MC it doesn't give me that option:
Secure Connection Failed
An error occurred during a connection to 131.111.10.92:4343. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem.
I can use Chrome instead which gives me the option to add an exception.
This particular controller did at one time have a different hostname. I've deleted my current exceptions but that doesn't seem to have made any difference. Note - we currently use the built-in certs. Could anyone explain what is likely to be happening here?
