But when I try to open node-red on the browser, the error shows: refused to connect. Can someone help in this ? When I type in node-red , I see the following screenshot on the putty, but nothing appears on the browser. Somehow I was able to start the node-red on the browser, using IP Address of IOT 2050 but it only starts when I type in "node-red" command on putty. Should it autostart without the command or have I overwritten something?

Usually when node-red is autostarted and you type in node-red, you will get an error message "Error: Port in use" - because you can't start node-red twice. You are sure that node-red is in autostart? Please provide the output of systemctl status node-red directly after booting. Best regards!

If you need to update or if you want to install it correctly with the Image you have running, you must do: - Kill existing service: sudo npm remove -g node-red node-red-admin rm -R ~/.node-red - The service that uses port 1880 must be killed: apt-get install lsof lsof -i :1880 kill -9 {PID} Attach images. I follow these steps to delete the Node-Red that comes from the factory in the Example Image. Then to install you can follow any page that indicates an installation of a recent version, for example: https://help.clouding.io/hc/es/articles/4414973151122-C%C3%B3mo-instalar-Node-Red-en-Ubuntu Attachment Doc13.pdf (618 Downloads)

I can burn the example image if that will fix the AutoStart thing! After following the steps in the above post and https://help.clouding.io/hc/es/articles/4414973151122-C%C3%B3mo-instalar-Node-Red-en-Ubuntu , I reinstalled Node-red : attached the screenshot below got this after self-signed certificate step. The node res still doesn't get AutoStartt, please see the errors in the above screenshot. Please help me with detailed steps Thanks Best Regards,

It sounds like a complicated process, but ultimately it's not. Once you have reinstalled the Image on your IOT, the node-red will boot without problems. Here you will see Bergmanu's explanations for reinstalling the OS on the IOT and some complications that other users have encountered in doing the reinstall. https://support.industry.siemens.com/forum/es/en/posts/how-to-setup-industrial-os-on-iot2050-advanced/266090/?page=0&pageSize=10

This can be useful if the reason for your crashes was a broken program: node-red --safe BR

Is there a way I can delete the OS or do a factory reset and then install the OS again? And also how can i check if my device came with Industrial OS or do I have to reinstall example image on SD Card? Best Regards
