# Description When a reconnect is rejected with a status that requires the endpoint to be refreshed, ManagedSession reads the endpoint again from the server's discovery endpoint and ConfiguredEndpoint.Update replaces the endpoint in use with whatever discovery returned. The application had no say: a discovery answer that, for example, drops the security mode or presents a different server certificate was taken over as it was. ManagedSession.ValidateRediscoveredEndpoint (a RediscoveredEndpointValidator) receives the endpoint in use and the rediscovered one before the session is recreated against it. A Bad result keeps the endpoint in use and fails the reconnect attempt with that result, so the reconnect policy decides what happens next. Without a validator the behaviour is unchanged. ## Related Issues None. ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [x] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [x] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [x] I have addressed **all** PR feedback received. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com>
