NPAPI disabled in the recent versions of Chrome
This article describes why Bosweb will no longer work on Google Chrome version 45 and higher. NPAPI has been disabled and the Java plugin will no longer work.
Bosweb will no longer load because the Java plugin is not detected in Google Chrome.
If you are interested in the specifics here is a blog written about it straight from Google.
As a temporary workaround, you may choose to use another browser such as Internet Explorer, FireFox, Opera, or Safari.
We are also piloting a new replacement for BosWeb that does NOT require Java. If you wish to participate in the pilot, please contact email@example.com and tell them that you are interested.
