    First, please make sure you have valid API-keys.And Try with Basic Authentication.
    Username:Consumer_Key
    Password:Consumer_Secret

    I have the same issue as well , and after searching with the check_oauth_signature in class-wc-rest-authentication.php that the problem is hash_equals( $signature, $consumer_signature ) return false. So I go through the whole variable related with $sinatue then something wired thing.

    $string_to_sign = $http_method . '&' . $base_request_uri . '&' . $query_string;

    $query_string would come with the header but if you set the Body into form-data on Postman that form-data would be coming with header(aww.. really ridiculous, rid off that). In my scenario, click the raw and JSON instead for form-data, the hash issue would strike.

    in the Postman, click in Params, create two Keys called "consumer_key" and "consumer_secret" and fills the values with API Keys (consumer key and consume secret generated into woocomerce). In Authorization tab do not fill anything.
