Unable to see Tag Providers using OPC Quick Client

Ignition
1

I’m running into an issue where I’m unable to view any of the tag providers that are configured in my gateway when I use the OPC Quick Client. I do have the Tag Providers folder listed, however, no folders are listed below. I get this error in the logs:

Do your tag providers have access controls that aren't satisfied for the Ignition OPC loopback connection?

How would I figure this out?

See if you have any security zones attached to your tag providers, and comparing to the default authentication profile used by the OPC server.
