I'm able to find your bot using either the simple or advanced search. Perhaps it was some network/infra blip? Can you confirm if it's still happening for you? (I assume you are in the correct sandbox environment - develop2.symphony.com)
You are right Yong!! Thanks for the answer. But I want to deploy my chatbot on the Pod Host that hired me as a developer. I tried to simply change the Pod Host but it raised an authentication error. I'm looking for answers. Once again, thank you very much
