2. When a site has a version of TLS that is not supported by the Java that is running the application, the crawler will not be able to crawl the site.

The crawler will retry several times.

You can also try increasing the timeout.  But first test to see if the TLS version is compatible with the java version you are using for Oracle Knowledge.

Changes

 If the TLS version was changed the crawl could stop working.
