We are using the [subscribe](http://files.inductiveautomation.com/sdk/javadoc/ignition79/795/com/inductiveautomation/ignition/common/sqltags/model/TagSubscriptionManager.html#subscribe-java.util.List-java.util.List-) method from TagSubscriptionManager to subscribe to all tag changes in a hierarchy. This works great on normal tag providers, but when we try to use it on a remote tag provider it fails silently (we just don’t get any triggers on the listener). 1. Any ideas why this doesn’t work? It seems like the general concept of a remote tag subscription exists (i.e. you can create gateway tag change events for them). Is it based on the recursive/hierarchal nature of the request (i.e. the same reason you don’t see a count of tags for remote providers from the gateway console)? 2. In a more general sense, any suggestions on the best way to subscribe to changes to all tags in a remote hierarchy? Thanks! ---

Anyone have thoughts on this? We’re kind of blocked on a major project by this issue. ---

Hi, First off, just to confirm, this is with the 7.9 sdk? And next, could you provide a few more details about how you’re subscribing? Are you actually creating a subscription for every single path under the hierarchy, or are you using a wildcard subscription? I’m not sure wildcard subscriptions are well documented, so you may not be aware that they’re a thing, but anyhow- let’s start with what’s going wrong, and then we’ll move to the “best” way to do it. ---

Hi Colby, We’ve tried with v7.9.5 as well as v7.9.10 . We’ve tried both ways ```auto singleTag = TagPathParser.parse(providerName, tagName); GatewayContext.getTagManager().subscribe(singleTag, listener); wildcard = TagPathParser.parse(providerName, "*"); GatewayContext.getTagManager().subscribe(wildcard, listener); ``` The same code works for a local provider but not for a remote provider. We’re sure the remote provider is online by accessing the values through the Status pages. Thanks. ---

I’ve retested.

Is more information needed to get reproduction steps for wildcard subscriptions of Remote Tag Providers?
