Hi,
I am having a problem converting a Curl command to an HTTP Request on a Teltonika Router.
Hoping there is enough information here!
The Curl command is:-
curl -X POST "https://<ROUTERIP>/api/login" -H "Content-Type: application/json" -d `{"username": "<username>", "password": "<password>"}` -k
With a Verbose response of:-
Note: Unnecessary use of -X or --request, POST is already inferred.

Trying to use the HTTP Request node, I get an UNABLE_TO_VERIFY_LEAF_SIGNATURE when injecting just the Payload (User/password).
In the Curl Command, I see SSL certificate verify result: unable to get local issuer certificate (20), continuing anyway. to overcome this I added msg.rejectUnauthorized = false in the Inject node. Now the I see requesting, and then after a time the HTTP Request node shows no response from server.

Tried all sorts of things and now I class myself as 'Officially Stuck', not sure where to turn next!
Any help would be gratefully received.
TIA
