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.

Have you tried accessing NR from a different machine than the Pi3? You need to know the IP address of the Pi. Let say it is 192.168.1.56, in a browser enter `192.168.1.56:1880` and see if you get into the editor.

In fact I was controlling the headless RPi with Vnc when the problem started. At first I thought it had something to do with Vnc so I rebooted and started control from the RPi itself. I still could not reach 127.0.0.1:1880.
It did not occur to me to try the RPi IP address with :1880 appended to it with Vnc. If the problem recurs, I will try that.
It has been working fine for the last few hours. I probably did something stupid and didn't realize it.
Thanks for helping.
