Help for https command

General
1

Hello
I use a device with wich it is possible to communicate with https requests.
So, I tried to use the http or even the https node (https contrib installed in adition to the stanard http)

Here is the command I need to send :slight_smile:
https://admin:mGuard@192.168.10.21/nph-status.cgi?path=/network/modem/stat
When I send this command with Chrome, for example, I get e reply as

/network/modem/state=offline

But i don't know exactly what to put in wich field of the http or https node.
For example, POST, GET, etc... ??? What must i use?

Most of times, no matter wich syntax I use, I get this

"Error: unable to verify the first certificate"

Can you help me, first to know what I must write in each field of the node, and then, if something specific must be done to send an https request.
Thanks

Seems like the device has a self signed certificate. Either that or the certificate is invalid for whatever reason. When you are testing in Chrome ( which is a GET request by the way) do you (or did you earlier) have to approve the certificate first?

Hello RealJax.
Yes, using chrome, before I send this request, I had to aprove the certificat.
And I confirm this is a self signed one.
How can I handle this in nodeRed?

Don't think you can. But maybe this page can help you further:

You can use LetsEncrypt to provide yourself with a valid certificate. It is not difficult.

The problem is that the device being talked to only seems to accept ssl connections ( which is rather odd I think) and then LetsEncrypt is not going to help.

Maybe putting the device behind a reverse proxy like Nginx first might work.

But @mike67 , assuming the device you speak of is a an MGUARD-router, have a look at this router settings to see if there's a way to disable SSL acces. ( and while you're at it, also change the default password :slight_smile: )

Hello
Finally that works
In fact, it was jest necessary to renew
the certificats.
And the Method is GET with user authentication

Thanks for your help
