Dear All,

I've done a fair amount of digging and I've not found anything that can help me on this one.

I've setup a wallet on my database and imported the following certificates.


When I run:

SELECT utl_http.request('',null,'file:C:\OracleDatabase\product\12.1.0\dbhome_1\owm\wallets\oracle','superman99') from dual;

I get:

ORA-29273: HTTP request failed

ORA-29024: Certificate validation failure

ORA-06512: at "SYS.UTL_HTTP", line 1491

ORA-06512: at line 1

Running it for is successful. even running it for is successful.

Naviaging to this i find a * certificate:


I've tried exporting and loading this certficate several times in severeal ways and in different formats but I always get the same exception:


I have tried removing all certificates except this one and I still get the same error.

My Oracle version is: Enterprise Edition

On: Microsoft Windows x86 64-bit

Update I found the following article, and I've tried removing the endpoint URL SSL certificate, but sadly it's still not working:

Thanks for your help!
