I stood up my own Joplin instance. I went to connect to my server, but am getting an error message. For the Synchronization Target, I selected Joplin Server (beta). I then typed in http: //my-ip for the Joplin server URL.
Here's the error message that I am receiving:
Error. Please check that URL, username, password, etc. are correct and that the sync target is accessible. The reported error was:
request to http: //my-ip/api/sessions failed, reason: connect ECONNREFUSED my-ip:80 (Code ECONNREFUSED)
The version of joplin server just shows latest, and the image ID is 0730bc78395e. My OS is Ubuntu 22.04.
