Hi @NirwalNeeti
The way cloud Galaxy is started up has changed a bit since that tutorial was published. Launch one from here instead: https://launch.usegalaxy.org/
Use the GVL version for the best performance and reliability (it is based on the Galaxy release 20.01)
The other Cloudman option is considered deprecated. So shut down and remove the old one, and start over with the GVL version. Your account at the new cloud server will be distinct from your accounts on any public Galaxy server.
Meaning, you need to add yourself as an administrator and create an account through the Galaxy website created inside the GVL appliance. Once both are done, you’ll be the administrator of the server with full control over configuration/administration (adding cluster nodes, installing new tools, and the like).

Thanks!
