Control update problems

Open Updates or the related Activity operation and read the current update state.

If Control restarted during the update, reconnect before assuming the operation stopped. Updates continue independently once submitted.

If the update reports a failure or rollback, keep the previous working version in service and correct the reported cause before retrying. Do not patch installed Control files or mix files from different releases. Use the supported update or rollback process.

If the Control UI is unavailable but the server is reachable, use the documented installed rollback/recovery procedure for that release and preserve the operation/error information for diagnosis.
