[jira] [Resolved] (HTTPCLIENT-1829) Apparently normal SSL site
generates a handshake failure
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleg Kalnichevski resolved HTTPCLIENT-1829.
-------------------------------------------
Resolution: Not A Bug
You might have better luck with other strong ciphers. Alternatively, try Java 9 or a different JSSE provider.

> HTTP client finds a redirect to

> But than it dies with the exception below. There is no problem with Chrome etc. or wget. We configure the client as

> .setRedirectsEnabled( true )
> .setMaxRedirects( 5 )
> .build();

> Hi,
> lately I've been seeing your Bubing crawler trying to retrieve
> http://isizulu.net/robots.txt but it doesn't seem to be capable of
> handling the redirect to https://isizulu.net/robots.txt so I am
> wondering what you have actually been doing during "the last ten years
> of research" as it says on your site (a minimum finding could have been
> that Java is just crap).
