Where the IP address shown here as 199.91.140.100:

Is the old data center IP instead of the new data center IP. This means that the proxy is still trying to connect to the old pre-AHA transfer data center IP address which is no longer the active data center.

If the reconnection was successful the above messages may still be seen in the log, however a successful reconnection would look like the following example:

2017-03-22 23:03:23,561 WARN Could not retrieve encryption configuration EdgeEncryptedFields(process). This proxy's status is not set to "online" in the ServiceNow instance "instancename.service-now.com:443". Will re-register with the proxy

2017-03-22 23:03:32,177 INFO Successfully registered this proxy "proxy01" with the ServiceNow instance "instancename.service-now.com:443"

When this problem is encountered the successful reconnection will not happen.

Workaround Restart the proxy

-- Windows: edgeencryption.bat stop, edgeencryption.bat start

-- Linux: ./shutdown.sh && ./startup.sh
