I am able to connect to the ODK Aggregate server from my phone over our wifi network, both through the web interface and ODK Connect. It allows me to view blank forms, but when I select a form and hit "get selected" I get an error:
failed to connect to /172.20.12.51 (port 10080) from /172.20.12.51 (port 52793) after30000ms: isConnected failed; ECONNREFUSED (Connection refused)
ODK Aggregate is running on the latest version of the VM and ODK Collect is the latest android app version.
