Unable to connect to TZ300 management interface
I'm trying to login to our TZ300 management interface which has worked fine for years. The last few weeks every time we try to login using a browser it gives an error. The errors vary based on the browser but all seem to be related to SSL. HTTP redirection is on so I can't login without using HTTPS.
I've tried multiple browsers and devices (including non-windows) with the same result.
Chrome: ERR_CONNECTION_CLOSED (Windows) or ERR_SSL_PROTOCOL_ERROR (iOS)
Any help would be appreciated.
