Node Red: http Integration: 301 error

[eng56]

Hello, I have a server where I'm running Node Red, I have just installed a LoriXOne gateway and I have set up gotthardp on it. I'm using the MQTT broker on node red with the following server adress: localhost:1883 , when I run it locally that's working. When I'm switching to another server who is not on the same network I need to change "localhost" by the server adress. How can I find it on gotthardp ?

I'm sorry if my question is stupid but I'm really stuck,

Thank you,

[gotthardp]

Well, the MQTT broker address is in the Connectors section.

Thank you for your answer, I think my question was not clear: I have a server with a websited hosted on it like: https://mydomain.com/nodered. My LoriXone is set up with Mosquitto and gotthardp. I'm trying to forward my data from my gateway to my nodered. I have tried with a MQTT node and also with a post request, both are not working. I have read and I have tried to do what you explain in your doc/Connectors and doc/Troubeshooting

Thank you for your time

This what I have done for POST, I have also a nodered running on the same network than my LoriXone, if I replace https://mydomain.com/nodered. by mqtt://localhost:1883 It working perfectly.

[gotthardp]

And where is your nodered accessible? This site says it may work with HTTP and port 1880.

[eng56]

My nodered is accessible via Internet, just have to browse to my http://domain.com/nodered. I'm already making POST with Sigfox or TTN, and it's working well. Thank you for your help

[gotthardp]

Well, it's hard to debug remotely, but:

• Try using http instead https as it's simpler
• Make sure there is a \ slash at the beginning of the Publish Uplinks and others (as described here)
• Make sure the port and path matches whatever is configured in your nodered.
• Read the debug.log to see if there are any errors or warnings

[eng56]

Yes I know and I'm sorry, thank you again for your help. . I'm using http . It should be / instead of \ no ? .For the debug I have an error of unknown_deveui, it's mean that the DevEUI is not correctly configured but I still have this error if I remove the connector and I let only the connector that is working (mqtt on local node red).

Thank you

Yeah, /, sorry for the confusion. I am lost a bit now. We should fix one error at a time. Please, get it working with MQTT (you must not see unknown_deveui) and then just change the URL and the /.

[eng56]

No problem. With MQTT set up to a local node red it's working. This the config that is working:

When I try to make a POST on my local node-red or on another node red in a distant server it's not working with this config: (I'm letting subscribed and received topic in blank because I just want to receive data)

[gotthardp]

I hope that you have server 0.6.x, your HTTP connector is Enabled and there is no Failed flag. Right? Is there anything in the nodered/server logs showing a HTTP error? Would you be able to operate https://www.wireshark.org/ to see what HTTP traffic is sent where?

[eng56]

I have set up my LoraW One yesterday so I think I have the last version. I have this error when I'm trying to make a post to my distant server (i don't have it with my local nodered): http_error{ 301,<<" http://mywebsite.com/nodered/public/lorawantest">>,<<"/nodered/public/lorawantest/lora/aiq/up">>}

Yes I know how tu use wireshark, I'am on the same Wifi Network than my LoriXOne do I need to install WireShark on it or can I use it directly on my computer ? I'm really gratefull for your help

[gotthardp]

Problem found: my server cannot handle "301" (sent by nodered) as already reported by #534 Can nodered be convinced to not send it? :-)

[eng56]

Ok thank you for your answer so it means that for the moment it's impossible to make a POST from Gotthardp to node red ?

[gotthardp]

Unless nodered can be convinced to not send it.

Ok thank you again for your help and your time
