After installed some expired certs on a server in house, I try and bring up a management page that worked fine prior. The error is: The server presented a certificate that contains an invalid encoding of an integer. Common causes include negative serial numbers, negative RSA moduli, and encodings that are longer than necessary. Error code: MOZILLA_PKIX_ERROR_INVALID_INTEGER_ENCODING How can this be worked around, a setting of some sort maybe? Thanks for any input
