Start ... and freeze?

General
1

I have installed the last version of Node RED on my Siemens IOT2040.

I have developped my Node RED software with the 0.18.7 version. Normally it take 6/7min to start.
It perfectly running with the 0.18.7 version.

I put my "flows_iot2000.json" on the Node RED folder (last version) and it doesn't start completly... after 3/4min it stop !
I don't understand ..

Have a look at the node red log on startup (the log that starts with Welcome to node red), that may well give you a clue. Post it here if it doesn't help.

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

Then stop ... and I can't access to :1880 to see Node RED interface

5

What happens when you try to access the web interface?
What do you see in the browser developer console when you try to access the url?

6

Nothing .. i have error 404

7

If you rename the folder containing the flows and settings file (normally .node-red but I don't know about that device) and restart node-red then does it work and if not what is in the log this time?

8

Yes, if i delete the flow file it work normally
But my flow file work on Node RED 0.18.7 with an other device (but exactly the same installation)

9

I try the same flow on a Raspberry with Node RED 0.19.2 and it work .. :frowning:
Is it possible it because the starting during 6 minutes ?

10

Have you tried waiting for a very long time to see if it eventually starts? Also watch the log to see if anything further appears.

I presume you saw the problem in the log with udp: port 1027 already in use. It might be worth sorting that out in case it is related. It might be some sort of network hang. Are you still able to access the PLC on the network when node red has apparently stopped?

11

Yes ... but nothing happen

Yes, it's possible to Ping and access with SSH

12

Are you going to investigate the port 1027 issue?

13

Hello, i'm investigating.. but i don't find anythink for the port 1027 ..

I have delete the udp node using port 1027 and i have the same problem. Loading is stop after 3 min...

16

I can't think of anything other than to start chopping bits out of the flow till it works and then put them back to find which bit is causing the problems. Perhaps someone else will have an idea.
