# Description Fail reverse-connect listener startup immediately instead of logging bind failures and surfacing a later connection timeout. - Validate and stage configured and programmatic listener endpoints before replacing active configuration. - Open all listeners atomically and report endpoint-specific failures with `BadTcpEndpointUrlInvalid`, the transport-specific status, or `BadNoCommunication`. - Roll back listeners opened by a failed attempt without reacquiring the manager lock, including forced listener disposal when normal close fails. - Preserve meaningful `ServiceResultException` status codes through both `StartService` overloads. - Dispose replaced configuration watchers and reject callbacks from stale watcher generations. - Keep the intended shared-listener behavior: one long-lived `ReverseConnectManager` can accept connections from multiple Servers on the same Client URL. - Expand `Docs/ReverseConnect.md` with listener lifetime, shared-manager usage, diagnostics, and specification references. ## Validation - `ReverseConnectManagerTests`: net10.0 and net48. - `ReverseConnectHostTests`: net10.0 and net48. - Ordered reverse-connect listener reuse integration tests: net10.0. ## Related Issues - Relates to #3985. ## Checklist - [ ] 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. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received.
