Error occurred while painting error page: ORA-01403: no data found ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1324 ORA-12570: TNS:packet reader failure
how can i solve this?

First of all ORA-20001 is a user-defined error.
I only re-ordered the first block. Changed the order of statements. Put exception just after select statement. Since, when exception occurs, DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE wouldn't run in your case.
