Unifi Nanostation Loco M5

[romaqld]

I have an issue with an older unit that hasn't had the firmware updated. It is running Firmware XM.v5.5.6 Build 17762 which is long since outdated.

I can sort of get into it using Safari on Mac but google or just about anything else I try I get similar to "This site can’t provide a secure connection 192.168.1.20 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH" and there is no way to bypass it.

Now I need to update the firmware but can't get it to load completely in safari to do that, I can click through to system and the upload firmware but as most of the graphics and interactive page doesn't load I can't actually upload and process that to do an upgrade.

I have tried SSH but that won't even prompt me for a password and dumps a key error.

Any ideas on how to solve this?

Should have an advanced option that allows you to ignore and go to unsafe site.
Ubiquiti always seems to come up with the error.
