We've developed a widget for Lotus Notes 8.5.3 and it was working fine. But after enabling our application servers for TLS 1.1 and 1.2 the widget can not be downloaded from the application server. During the download, the Lotus notes client is giving following error.
In the client logs, following error can be found.
"javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake"
Note that a correct certificate is used and that certificate is working in all other clients without any issue. Lotus notes also correctly imports the certificate as an internet certificate. But still the above error exists.
We suspect this is due to an issue in the Notes and found the fix https://www-10.lotus.com/ldd/dominowiki.nsf/dx/TLS_1.2
Will this interim fix solve our problem? Or we need to do any other additional changes/configurations to solve our problem?
Thanks and regards,
