Firstly the browser is probably not supported with a 10.1.2.3 OHS/WebCache.
Additionally, you are using SSL. A lot has changed since 10g was supported product. For instance your browser may only connect to TLS1.1/1.2. 10.1.2 topped out at TLS 1.0 and that was with a patch.
Check the server logs.
Have you tried this with 11g or even 12c?
