AEM 6.4 Link Checker SSL Error

Hi,

I am facing issues with some external links getting removed by the link checker.

While checking in /etc/linkchecker.html , it shows the links are invalid and throwing a SSL error. The same url works fine in the 6.2 environment. I  have not made any modifications to the link checker configurations in either environment. Kindly let me know if any new changes to the 6.4 link checker service might be causing this and how to go about resolving the URL ? I am hoping not to disable the checker altogether.

    What's the message in the log about this "SSL error", can you be more specific. I doubt that there is a regression, but my first bet is that your AEM 6.4 environment is configured differently than your AEM 6.2 environment. Maybe missing SSL certificates?

    Hi,

    Sorry, I tried to add a picture attachment and it may have got deleted earlier. When I access /etc/linkchecker.html, this is the error I get

    Also, I get the below error log for an 'Invalid' and 'Valid' link respectively.

    Invalid :

    25.07.2018 01:06:46.465 *ERROR* [sling-default-3-com.day.cq.rewriter.linkchecker.impl.LinkCheckerTask.23680] com.day.cq.rewriter.linkchecker.impl.LinkCheckerTask Failed to validate URL http://xxxxyyyzzz.com/xyz/overview.aspx: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    Valid :

    All this is happening on my local instance, so there are no certificates etc installed for this.

    Hello Jörg Hoh ,

    I am facing the same issue mentioned above. Obtaining a new valid certificate is not an option as it takes a few months and the client requires this urgently.

    In previous versions, the LinkChecker was ignoring this SSL issue via the service.check_override_patterns property, which had been working for some years now. This seems to be an issue with 6.4 only, so I would kindly appreciate your support. Is this a regression?

    Best regards,

    Gio


    This property still exists (checked on my local 6.4 env here).
