My bash script:

Code:

JF="http://192.168.2.23:8096"

#Login
read -p "$JF | Username: " username
read -sp "$JF | Password: " password
data=$(cat <<EOF
{
    "Username": "$username",
    "Pw": "$password"
}
EOF
)


curl -X POST $JF/Users/AuthenticateByName \
          -H 'accept: application/json' \
          -H 'Content-Type: application/json' \
          -d "$data" \
          -vvv

And the error:

Code:
