It works! Thank you

Hi @willwetherman    thanks for your post. I think the TLS Verison is the problem. A few weeks ago I changed the TLS minimum version to 1.2 because of some customer policies. I will go back to 1.0 and test again...   Thank you

I have the same problem. Any Update?  

Hi Mirandathanks for your suggestion. But this replacement workflow is no help if you want to add stackmembers to an existing Stack.Maybe there will be a Workflow for Adding Stackmembers in the future? 

We have the same problem! the only solution is to copy and paste the interface config from the existing stackmembers to the new stackmembers over CLI and reload the whole stack...
