Hi Dojo,

I've been seeing the following issue when trying to renew the cloud session through Client Test Tool:

I noticed the issue because I saw the following in SLErrors:

I tried restarting NAS and NATS as well as reinstalling them as described here. I tried reinstalling CloudPack, both with and without .NET. I tried restarting bunch of services like CloudGateway, CoreGateway, BrokerGateway. I also tried reinstalling couple of modules from C:\Skyline DataMiner\Tools\ModuleInstallers. I've confirmed that port 4222 is open. NATS logging shows no errors and that "Streaming Server is ready".

One other thing that I find peculiar is that SLCloud.xml is not automatically adding IP when I delete old one. This used to be the case, if there is no IP defined in SLCloud.xml current would be added on startup. I've updated the CloudPack to latest version on Monday but everything worked fine yesterday and the day before.

I'm using DMA 10.5.7.0 - 15952 and CloudPack 3.3.3.0.
