API not quite working

I tried to connect to a local device with the API in Windows 10. I use the command

curl -k -c cookies.txt -H “Content-Type: application/json” -X POST -d ‘{“username”:“admin”,“password”:“8characters!9”}’

from the command prompt with admin rights. What I receive is a

“stat”: “fail”,
“code”: 301,
“message”: “Unauthorized”

altough the user and password is correct. I tried manuals, the forum and so on. What am I doing wrong?

Hi @Dude2048 welcome to the forum. Login example from device API manual should work:
curl -c cookies.txt -H “Content-Type: application/json” -X POST -d
Link to the latest manual:
Do you have Redirect HTTP to HTTPS disabled under System > Admin Security ? This error can be seen most of the time due to wrong used login credentials.

I used the latest manual, latest firmware, http to https direction (hence the -k option in curl to suppress the certificate). The command I used is the same that you gave to me.
Hardware used is a HD2 MAX hw revision 2.

Any update on this?

We have tested again, in firmware 8.1.2, the result is successful, using MacOS.

At the same time, we also tried with Windows 10 cURL to the same router and it exhibits the same output as yours.

Which/what cURL tool are you using for the testing?

I’m using windows 10 i have a mac at home i may need to try. Thank you for the response
