I suddenly can't open Node-RED running on RPi3A+. I have Node-RED as a bookmark with the address 127.0.0.1:1880/#flow/27d1362d.4b7eda. After startup and a little wait, I get these messages when I use the bookmark: "This site can't be reached" "127.0.0.1 refused to connect".
When I try to open Node-RED from the programing menu, I get this error message: "failed to execute child process "xterm" (no such file or directory)".
I have rebooted several times. I don't know Linux well enough to go into the console to troubleshoot this.
Help, what has gone wrong?
This doesn't make much sense to me but out of desperation, I clicked the h274ify Options button on the browser. I didn't change anything, I just wondered what it was. Suddenly node-RED popped up in the browser.
