Cannot connect to NAS after upgrade to DSM version 6.2.1-23824. It says "Connection failure". Update: it works only with HTTP, not with HTTPS, but I don't know why, it worked before upgrading.
It sounds like you need to use an HTTP certificate that your browser accepts and/or you're using the wrong port. In the case of the certificate, the extension is not capable of letting you add an exception like you can in normal browsing, so you need to specifically accept your certificate browser-wide for it to work.
