Failed to established Deluge PRC connection

[smashkins]

I am using docker and setup both deluge and storm under a bridge connection on Synology Nas.
Error received:

environment:
      - DELUGE_RPC_HOSTNAME=deluge
      - DELUGE_RPC_PORT=58846
      - DELUGE_RPC_USERNAME=localclient
      - DELUGE_RPC_PASSWORD=<redacted>
      - DELUGE_RPC_VERSION=v2

Obviously the password is correct and I can access to deluge web ui

The RPC password is not the same as the Web UI password. Have you checked that you're using the right one?

To complete @relvacode's answer, you need to add a new user to your "auth" file (which is in the deluge config volume).
You cannot use the webui user ((localclient), I was stuck for a while trying to figure this out.
The password doesn't have to be encrypted, follow this page: https://dev.deluge-torrent.org/wiki/UserGuide/Authentication
(level 10 works, idk if you can use a less privileged level).
Don't forget to stop the deluge container before editing any config files
