Filr configured with TLSv1.2 breaks GW integration

Filr 3.2 servers can be configured to use TLSv1.2 only (no fallback). When the Filr server is configured with TLSv1.2 only, it breaks the GW integration.

STD :

-  Filr configured with TLSv1.2 only

- Start GW client

- New email

- Add Attachment

- Click the Filr Reference button

Now the attach file windows is gone an nothing happens after this anymore, the new File attach window that should be there with the Filr file structure never shows.
