There are two ways to handle it: 1. set client lifetime to some suitable amount at oxauth configuration `dynamicRegistrationExpirationTime`. (If set it to 1 year then all dynamically registered clients will have 1 year lifetime.) 2. You can call `update_site` command against oxd-server to extend expiration time. For this you can use one of our libraries, please check documentation here https://gluu.org/docs/oxd/3.1.3/libraries/api-client-libraries/ and here https://gluu.org/docs/oxd/3.1.3/faq/#how-can-i-avoid-client-expiration Thanks, Yuriy Z

Thank you for your response! I managed to execute the update_site command. I am using the php sample app (https://github.com/GluuFederation/oxd-php-library/tree/3.1.3/client.example.com). But when I execute the update_site command I get the same error: 'expired_client : Invalid oxd_id. Client is expired.'. Is it possible to update the already expired client (in this case the konga client for the Gluu Gateway admin portal)? Or should I setup a new client and/or register a new site with the setup_client and register_site commands?

Hi Julian, We can update only not expired clients. When client is expired it is scheduled for removing on OP, so at the time you call `update_site` for expired client, it can be already removed on OP. Thanks, Yuriy Z
