I have gotten the same error message and I had the time synched with the browser. when I opened the detail message ( see the attached) It showed that "request to https://registry.npmjs.org/ node -red-contrib-ui-led failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org" I have been using a company issued laptop and had the ctrlX connected to the internet port of the laptop and used wifi to get internet connection. based on some suggestions from google I set the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0'. it still didn't work. I tried to do the same at home and got the same error. is the company server blocking the registry website? why did it not work at home without VPN connected? please let me know if there is a way to get it worked in the office since in the future we will work in the office. Thanks,
