deepin Transmission Remote, as its name suggests is to remotelly connect to another running Transmission instance, typically in another computer in the same network.
It's also possible to use this feature when enabled in the actual Transmission to connect to it from another software in the same computer (e.g. Kodi with the Transmission plugin) to observe the progress of the downloads and other functions.
In conclusion, you need to understand Transmission Remote is NOT Transmission. It merely connects to an host running somewhere else. Your own screenshot shows a blank host so it couldn't possibly work. You must start the actual Transmission. Then, if you want to control it from another computer in the network, enable and configure remote access in Preferences - Remote: Tick "Allow remote access", keep or change the port, authentication, etc.
Hello...
My name is Allan and I'm new to the linux system... I studied the decision to dedicate myself to the system for months... now I'm learning and with some doubts... many I managed to solve with a lot of research, others like this one I'm looking for help from friends. ..
Whenever I start transmission it doesn't connect, which prevents me from downloading torrents.
Thank you very much in advance for the attention of anyone who can help.
