#### What product/components do you use and which version/fix level are you on? Cumulocity 10.6 #### Is your question related to the free trial, or to a production (customer) instance? Production #### What are you trying to achieve? Please describe it in detail. Trying to add an OPCUA server and scan the address space. I was able to connect to the OPC UA Server but the auto address space scanning never completes, it left in executing state due to this I am unable to see the address space in the address space tab and not able to create any device protocols. OPCUA server connected ![image](https://europe1.discourse-cdn.com/flex005/uploads/cumulocity/original/3X/c/b/cb80d15d27d76bbdca86fe977b495d6c50872e71.png) Operation is in executing state, never set to complete ![image](https://europe1.discourse-cdn.com/flex005/uploads/cumulocity/original/3X/7/a/7af85ad39a7fb856085e24da4ac915f0803bd40d.png) Nothing shows up in address space ![image](https://europe1.discourse-cdn.com/flex005/uploads/cumulocity/original/3X/3/f/3f4c65c7bde73dd79a54d94e1bb3f9842c59a51e.png) #### Do you get any error messages?
