Node-Red Data Layer subscription node cannot subscribe data layer value.

[YO-LS]

Hi community,

I currently facing a problem on Node-Red which the datalayer subcribetion node cannot subcribe the value from data layer. The Node-Red version that I using is 2.4.0 and using ctrlX CORE Virtual Version 2.04. Do anyone faced this issue before and how you resolve it?

As error points to connection setting problem:

• What are the settings of your subscription?
• Do the user have sufficient rights to access these variables?

Hi @CodeShepherd,

I think user have sufficient right to access these variables since the operation of the variable is read.

Below is more information for the subscription node:

Hi @YO-LS ,

From the image in your original post, it looks like you might not be able to browse the datalayer in the Datalayer Subscribe node? If you can't browse the datalayer and select the endpoint you'd like to subscribe to, there is definitely a connection issue. 

Can you please post the configuration of your "localhost" device used in your "Python state" subscription? Please double check the the credentials and network configuration in this device.

Hi @Sgilk ,

Do you mean this?

In the screenshot you send there is no user and password configured. Please enter the right credentials of your ctrlX CORE here.
