Troubleshooting Guide and FAQ List

Known Issues

In some cases, the Azure services we rely on may themselves be down. This is not a problem with the Decision Service itself. Please retry your deployment at a later time; if the problem persists, please open an issue here if one does not already exist. Our Github issues page is also a good source for finding potential solutions to your problem.

"HTML5 Storage Disabled" in Internet Explorer (IE)

Cause: A limitation of certain versions of IE.

Solution: Run IE as administrator and/or check the “Enable DOM Storage” box in IE tools/Internet Options/Advanced/Security/.

Deployment fails because 'The location constraint is not valid'.

Cause: Your Azure subscription does not have the rights to deploy one or more of the Decision Service components in your chosen region. In particular, we make use of the "Classic Cloud Service" resource which by default is not always supported in all regions.

Solution: Retry in a different region, or open an Azure ticket to request additional account privileges. An alternative way to find out which region you have access to is to manually create a new Classic Cloud Service: In Azure portal, click on New -> Cloud service (classic) and select a location. If the location is not supported, you will get a red exclamation mark.

After clicking Deploy To Azure, I get redirected to the Azure portal page but nothing shows up, what to do?

The portal sometimes fails to open our deployment template, simply retrying should fix this.
