My build failed with an exceptont:

talaiot version 1.5.1
This exception throws only on teamcity build agent.
I found discussion about this problem https://stackoverflow.com/questions/1881546/inetaddress-getlocalhost-throws-unknownhostexception and ask devops to configure build agent.
But in my case it is not always possible to configure build agent and this one maybe one of them.
Hi, thanks for the issue. I merged a quick fix to avoid the exception.
The StackOverflow link that you sent explains the issue:
It seems that InetAddress.getLocalHost() ignores the /etc/resolv.conf, but only looks at the /etc/hosts file (where I hadn't specified anything besides localhost)
Apparently we can rely on NetworkInterface.getNetworkInterfaces() as a fall back when InetAddress.getLocalHost() throws an UnknownHostException. In the initial fix I just catch the exception. I can deploy a new version in a couple days.
