I have a procedure which sends error (a message) over a URL. The ACL has been defined and the procedure works fine, But when I try to call this procedure from another procedure which is inside the same package, it throws me the following error.

ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1369
ORA-29263: HTTP protocol error

The procedure is
PROCEDURE SEND_ERROR(P_MESSAGE_ID VARCHAR2, P_ERROR_MESSAGE VARCHAR2)
AS
L_REQ UTL_HTTP.REQ;
L_RESP UTL_HTTP.RESP;
L_STATUS_CODE VARCHAR2(100);
L_REQ_STRING VARCHAR2(4000);

BEGIN

L_REQ_STRING := 'http://127.61.9.4/TestUrlParamsEcho?messageId=='||P_MESSAGE_ID||'&errorMsg=='||P_ERROR_MESSAGE;

--Making sure than the spaces in URL are replaced with %20
L_REQ_STRING := REPLACE(L_REQ_STRING,' ','%20');
--Making sure that the URL string is less than 2000 characters
L_REQ_STRING := SUBSTR(L_REQ_STRING,1,1990);
-- Trim the end of the string if it has %20
L_REQ_STRING := RTRIM(L_REQ_STRING,'%20');

--Begin Request
L_REQ := UTL_HTTP.BEGIN_REQUEST(L_REQ_STRING);
--Get Response
L_RESP := UTL_HTTP.GET_RESPONSE(L_REQ);
L_STATUS_CODE := L_RESP.STATUS_CODE;

INSERT INTO STATUS_CODE_RECD (STATUS_CODE, RECD_TIME)VALUES(L_STATUS_CODE,SYSTIMESTAMP);

END SEND_ERROR;
---------------------------------------------------------------------------------------------------------------------
This procedure runs fine when I pass parameters.
---------------------------------------------------------------------------------------------------------------------



Then I tried to call it inside the following cursor

OPEN C_ERROR_DATA;
LOOP
FETCH C_ERROR_DATA INTO L_MESSAGE_ID, L_ERROR_MESSAGE;
EXIT WHEN C_ERROR_DATA%NOTFOUND;
SEND_VALIDATION_ERROR(L_MESSAGE_ID, L_ERROR_MESSAGE);
END LOOP;
CLOSE C_ERROR_DATA;
---------------------------------------------------------------------------------------------------------------------

ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1369
ORA-29263: HTTP protocol error

Thanks in advance.
