Check the expiration date of the TLS and L2 certificates.
Determining the L2 Certificate Expiration Date
The Nymi Enterprise Server(NES) L2 certificate needs to be renewed before expiration. If the L2 certificate has expired, Nymi-enabled Application(NEA) token renewal is not possible and results in service disruption.
Determining the TLS Expiration Date
For NES servers that are configured to use https, the NES TLS server certificate also needs to be renewed before expiration. If this certificate has expired, most CWP services cease to operate. Customers are responsible for renewing the NES TLS server certificate.
