I double and triple checked that user id and password are entered correctly, but I cannot get USPS shipping quotes to work. In debug, I get the "Illegal scheme supplied, only alphanumeric characters are permitted" error. base url and secure base url look correct to me.
[2017-05-11 14:28:34] main.DEBUG: array (
'request' => '<?xml version="1.0" encoding="UTF-8"?>

',
'result' =>
array (
'error' => 'Illegal scheme supplied, only alphanumeric characters are permitted',
'code' => 0,
),
) {"is_exception":false} []
Any input is greatly appreciated, I have been trying for a day to fix it without any luck...
