We have just released Fusion Server version 12.16.2 to address this issue. If you have already upgraded to 12.16.1, please upgrade at your earliest convenience. If you have questions or concerns, please reach out to our support team.

Our testing is nearly complete. Baring any last minute setbacks, we will have an updated release of the InformaCast Fusion Server soon.

A fix has been implemented and is currently being testing. We will update this incident when testing has been completed and we are ready to move forward with making the fix available.

We have released a specific knowledge base article with more detailed instructions to restart problematic Fusion Server. Please visit: https://support.singlewire.com/s/article/Server-is-experiencing-difficulty-communicating-with-InformaCast-Fusion-after-upgrade-to-12-16-1

Fusion Servers that have been upgraded to 12.16.1 may lose communication with the cloud-portion of Fusion. This appears to be caused by Fusion Servers temporarily losing network connectivity and not attempting to reconnect. We're actively working on a fix.

As a work around, you may reboot any affected Fusion Servers or follow the link below to restore communication.
