SDK Cannot deploy to emulator anymore

I give the fancy search here in this forum a try (!) and got:

SDK 3.2: unable to deploy package to emulator with Docker based build engine

It should not. But your question made me realize, that there is still one piece of the puzzle missing: The NAT configuration of the emulator virtual machine. If you open the settings of the virtual machine (In Oracle VM VirtualBox Manager), you will find “Port Forwarding” in “Network” settings. There is a rule “guestssh4docker”, which quite likely has “172.17.0.1” as the host IP. You should change that to 100.64.0.1 as well.

There is also an ip address of the emulator for testing connections..
