TLS secured connection via browser

Hi,

I used Mesh Commander to setup a TLS secured connection, using a self issued certificate. The connection works fine via Mesh Commander.

However, on certain devices I can only use the browser interface. I can connect via Android for example, without TLS enabled, but need this to work with TLS.

As a test I imported the user certificate into firefox, and tried to connect via port 16993 with TLS enabled.

I receive SEC_ERROR_UNKNOWN_ISSUER so I added the address as an exception, then I get SSL_ERROR_BAD_MAC_ALERT.

How can I use the browser interface with TLS enabled? (or alternatively, is there an Android app where this is possible?)

Much appreciated!

Thanks
