Previously undiscovered issue in Station Manager 5.5

Station Manager version 5.5.5 has been deployed and is now available. This new version is considered a mandatory upgrade to 5.5.0 as it includes the critical fix to ensure proper connection to our CDN in the future.
Clients can find the download link in our Station Manager Release notes (https://help.tritondigital.com/docs/sm-release-notes) or via our permanent latest version link (https://provisioning.tritondigital.com/station-manager/StationManagerSetup.exe).
We advise all clients using Station Manager 5.5.0 to make plans to upgrade to the latest version at their earliest convenience.
This incident is considered resolved.

We have identified the necessary fix to implement in Station Manager. Once the bug fix goes through our QA phase, a new version of SM will be released on our User Guide pages. We will update this incident with the necessary information at that time.
More information to come.

We have deployed a partial fix for the issue in our back end services. This should remove the need for downgrading to Station Manager 5.2.6.
A coming update to Station Manager will further improve things.
More information to come.

We are investigating a previously undiscovered issue in Station Manager 5.5. Under very rare circumstances, Station Manager version 5.5 may encounter an error while trying to interact with Triton Backend Services, resulting in the program becoming unable to initiate streaming of stations. Users will then see the following error in the Station Manager logs: “Error - Module=SmIdProvider : Problem communicating with dedup service”.
If you encounter this error, we advise to downgrade the installed version of Station Manager to version 5.2.6 (available here: https://help.tritondigital.com/docs/sm-release-notes). Make sure to create a backup of the configuration files , uninstall SM and install version 5.2.6. Contact Customer Support (supportdesk@tritonditigal.com) should you require help.
Pleas note that we do not advise a preemptive downgrade. SM 5.5 contains several important features and fixes which SM 5.2.6 does not have. A downgrade should only be applied if the aforementioned error is present and stations are not streaming.
Our team is currently working on a hotfix.
