Randomly receiving connect ETIMEDOUT 52.1.223.15:4443

Hello,
We have multiple Asana integrations. Randomly some of them are receiving error:

Error: connect ETIMEDOUT 52.1.223.154:443
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1191:14)
[stack]: ‘Error: connect ETIMEDOUT 52.1.223.154:443\n at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1191:14)’,
[message]: ‘connect ETIMEDOUT 52.1.223.154:443’,
errno: ‘ETIMEDOUT’,
code: ‘ETIMEDOUT’,
syscall: ‘connect’,
address: ‘52.1.223.154’,
port: 443

The IP address is not always the same. Is it some kind on restrictions or Asana API is blocking our side?

Any updates?
