Can't connect to Firmware Update server

Hopefully I’m in the right forum this time. Thought I had a MyCloud Home but was told it’s a MyCloud Mirror.

My firmware version is 2.10.310 which I gather is too old to auto update but based on my P/N my drive does have an update but it needs to be done manually. But it appears it needs to be done in 2 steps?

Is there a page you can direct me to that will walk me through the steps?

Thank you!
