Workaround for ERR_SSL_VERSION_OR_CIPHER_MISMATCH problem for Sparc NAS (4.1.x firmware)
This workaround eliminates the redirection of http://nas-name-or-ip/admin to https://nas-name-or-ip/admin for NAS running 4.1.x firmware. It does require ssh to install.

The ERR_SSL_VERSION_OR_CIPHER_MISMATCH error typically happens on older operating systems or browsers.
But that is not always the case. In fact, we just recently encountered a user having this issue on their WordPress site who was migrating to Kinsta from another host. We were, of course, running the latest version of Chrome, so the issue was with their SSL certificate. Chrome is actually protecting you by not letting you load it.
You might also see a variation of the error, such as:
- Error 113 (net::err_ssl_version_or_cipher_mismatch): unknown error
- The client and server don’t support a common SSL protocol version or cipher suite

Not true. It's happening with current Chrome/Edge/Firefox on any OS. Probably current Safari also, but I haven't checked that.
Older browsers might give cert errors, but not this particular error. This is about browsers dropping support for TLS 1.0/1.1, and requiring TLS 1.2. It has nothing to do with certs. It's because the older ReadyNAS don't have TLS 1.2.
