Dear All,

We purchased the Ignition Edge/Sync and OPC UA license 3 year ago and installed it in the Ignition Edge server on \_08-07-2023.  
But, now we have check OPC UA security page on ignition gateway and find OPC UA server/client certificate is expiration on 08-Jul-2023.

So, please guide us for continuous working OPC UA without any disturbance.

Thanks,  
chirag k

You must generate a new certificate. There will be slight downtime while you have the new certificate accepted by each end of the communications. If you can upgrade to a current release, you can use the gateway's new UI to generate the new certificate with expiration many years in the future, instead of three years.
