Hi @vant
First, please try again since this type of connection issue is usually temporary. Delete the existing job to clear it, then create the environment from scratch again. Be sure to only be running one interactive environment at a time.
Then, if you are still have problems, would you share the full URL to the Galaxy server where you are working again? You named the link for one server, then the link itself was for a different server.
Or better, you could also share your history where the environment is running from. How to share is in the banner of this forum, also here.
Let’s start there, and let us know if you solved this already!
