The last command is
$ cat /var/log/kaa/* | grep ERROR
and the error occur

I'm trying to start up Hazelcast on AWS ECS. I have gone through the tutorial and have enabled all the permissions on the task role i.e decribeTasks, lisTasks etc. I have have a very simple configuration file
hazelcast:
cluster-name: hs-dcom-hazelcast
network:
join:
multicast:
enabled: false
aws:
enabled: true
interfaces:
enabled: true
interfaces:
- 10.106.*.*
However when the container tries to start it throws the following error

I want to fork the waves blockchain in which I wanted to change the coin. I first change the name of coin in waves node
link : https://github.com/wavesplatform/Waves/blob/version-1.2.x/node/src/main/scala/com/wavesplatform/transaction/assets/exchange/AssetPair.scala
according to the link I deployed on windows and I got this error.

Im trying to connect from an basic Milo-Client (ReadSample), but getting UnresolvedAdressException. Both Client and Server are in an remote Network and I only got Access to the Client. I'm pretty sure its not a Firewall since I can Connect with other Clients (Prosys OPC UA Client) and i can see that the ip is resolved to an Host-Name in the Logs:
Server is opc.tcp://192.168.115.40:49580 aka opc.tcp://Extern-Mess-Rec:49580 (tried both in UaTcpStackClient.getEndpoints(url).get();)

The server you're getting endpoints from is probably returning "Extern-Mess-Rec" as its hostname, which you can't resolve.
See this answer for how to deal with that scenario.
