Got up this morning and NR is not working

General
1

Yesterday evening all was ok.

This morning I got up and didn't really take too much notice but I got home abut 11:00 (local time) and tried to connect to my main NR machine.

This was brought on by a device which talks to NR (and vice versa) wasn't playing the game and the display was turned off.

So I thought I would look into it.

Page refused to load.

Looked at the syslog and saw this (again: see attached.)
I haven't done anything to it in the mean time.

I have rebooted, powered down, waited and powered up the machine.

NR still refuses to show me a web page.

This is what NR tells me if I ask for a status:

But when I try to go to the URL...

(See picture 1)

Sorry, but I'm stumped.

Looks like you have the same problem I had last night, except mine started at midnight by turning on and off because I have it so that if it shuts down it automatically starts back, so guess how I felt... any way the problem is the bigtimer node I downgraded mine to 2.0.8 and that fixed the problem. to revert back if you are unsure you do the following a a prompt npm install node-red-contrib-bigtimer@2.0.8 of to what ever version you like.

Yeah, funny you should mention that.... Bigtimer.

I found posts on it and this is a confusing thing I just saw:
Given there is problems with a new(er) version and all that, I decided to try "rolling it back" to 2.0.9 with npm from the CLI.

But I'm confused with what the CLI is telling me.
Not sweating on it too much, as it does seem to have fixed the problem, I don't get why I am being told something different to what is* happening.
npm install .......@2.0.9
Removing .... @2.1.3 from the tree as **it is been replaced by a newer (version?)
2.0.9 is newer than 3.1.3?

Just as a follow up on that.

That was on "machine #1"

Looking on this machine I have bigtimer 2.1.1 and it seems to be ok.

So maybe you could get away with 2.1.1. How 2.1.3 got on my machine is interesting.
Maybe I did update it, but can't be sure.

I am updating that machine to 2.1.1 and shall indicate if all is good or not.

I had the same issue over the weekend. I updated bigtimer and it went away.
