Via Curl:
curl -k https://<AriaAutomationFQDN>/config.json | jq -r '.applicationVersion' | base64 -d
Via Web Browser:
1. Open Web Browser and url:
https://<AriaAutomationFQDN>/config.json
2. document the value for applicationVersion
3. Decode the applicationVersion value from its base64 value. You can use the openssl command in windowd command prompt
echo <applicationVersionBade64EncodedValue> | openssl base64 -d
So for the example given in the screenshot above:
echo Vk13YXJlIEFyaWEgQXV0b21hdGlvbiA4LjEzLjEuMzIzNDAgKDIyMzYwOTM4KQo= | openssl base64 -d
Alternatively there are a number of online tools which offer free base64 decoding functionality
