exchange 2010 to 2016, access EAC, get http 500 error if old exch svr down

I am migrating from exchange 2010 to 2016 in a test environment. When I click on the Exchange Administrative Center from the 2016 server's desktop, I accept the certificate warning, sign in, and then get an HTTP 500 error. This only happens when the 2010 server is down. I have cycled the 2010 server several times: When 2010 up, it works. When 2010 down, 500 error.

This is a test environment and this is my second pass at this. The first pass I didn't notice the problem until after uninstalling exchange 2010, and couldn't get in.

Am I missing something?
