I had the same problem. I configured first a deployment server and then the remote interpreter using the same deployment server config. I was asked if I want to either create a copy or move the configuration from the project level to the IDE level. I moved it.
The problem is that the credentials for the server are only available on the project level. To solve it I had to:
- go back to the Deployment Configuration
- click on these “…” till I reached the “SSH Configurations”
- Unchecked the “Visible only for this project” checkbox
