Node-Red Blync Node Ubuntu AWS Connection Problem

[Trevor Daniel]

I have an AWS instance running Ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-1052-aws x86_64)

I have Node.js version v9.4.0

I have Node-Red v0.18.3

I am attempting to get any Blync node to work.

I have attempted to install and configure 2 different offerings and neither will work. Reporting that they cannot connect to the server.

I have added the inbound port 8080 to the AWS Security group.

Apart from opening that port is there something else I should have done

Can anyone help me debug this problem? How do I get to any event logs on the AWS box to try and see any error messages?

Any help would be greatly appreciated!

I have managed to get to the Node-Red logs and this error keeps occurring:

0|node-red | open
0|node-red | handle login 187f15b3f3af4f40affccc313feb7b84
0|node-red | Unhandled response { type: 41, typeString: undefined, msgId: 1, status: 19 }
0|node-red | close

I have uninstalled the previous Blynk node and now installed the node-red-contrib-blynk-ws node and now I get these errors:

0|node-red | 25 Feb 12:46:54 - [info] [blynk-ws-client:Weather Station] Start connection: ws://blynk-cloud.com:8080/websockets
0|node-red | 25 Feb 12:46:54 - [info] [blynk-ws-client:Weather Station] login -> 187f15b3f3af4f40affccc313feb7b84
0|node-red | 25 Feb 12:47:09 - [info] [blynk-ws-client:Weather Station] Connection closed: ws://blynk-cloud.com:8080/websockets

It seems unlike that there are problems with both the nodes I have installed as Palettes.

So, there must be something wrong with my server?

Or have I forgotten to enable something on Blynk?

Desperate to get this working lol!

Those three messages are Info rather than errors

But if it's still not working you could try on the recommended nodejs version (Node.js LTS 8.x.) and see if it is a change in v9 thats causing the nodes not to work.

Many thanks for taking the time to look at my issue.

I am now getting this error:

For websockets do I just open TCP port 8080?

I have just checked the address for the Blynk server and it connects using this website...

Exactly the same issue here, Trevor. Have you found a solution by now?
