Docker NodeRed Install Fail

Tags: #<Tag:0x00007f32704417f0>

Hi all, this is my first time on the community I have been dabbling in HA for almost a year and ready to plunge in head first!! I have a network server running docker. Portainer is fine, HA, MQTT is fine but I can’t get the NodeRed to open I know this is not strictly a HA question but from what I have seen from many community members YouTube videos NodeRed is critical. I installed using the Docker command line exactly as per the instructions on NodeRed (https://nodered.org/docs/getting-started/docker) but when I go to my server ip:1881 there is nothing there.

I can’t understand why. Same is happening to my Plex and OV5 installs to which I want to integrate into LoveLace later.

Any tip on where to look next with would be greatly appreciated.

Thanks,
Izzy
