Not Connected Issue #21

Closed asimsinan closed 6 years ago

asimsinan commented 6 years ago

I have two nodes running in Amazon. However, I see "not connected" . Is it because I don't have enough nodes or is it related to nxt properties file? 2 is not enough? Genesis accounts and everything is okay. I opened all three ports from amazon. screenhot.

When I try forging I get the following error 2018-10-28 15:56:35 SEVERE: Error in block generation thread java.lang.NullPointerException at nxt.Generator.setLastBlock(Generator.java:323) at nxt.Generator.access$400(Generator.java:40) at nxt.Generator$1.run(Generator.java:79) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748)

Have you set in your nxt properties file the ip of the nodes? Or try to add nodes through the interface.

asimsinan commented 6 years ago

Yes I added them to nxt.wellKnownPeers.Did the same thing from interface, it says "already added". However, I managed to forge. Now there is no error. There is another interesting thing. When I copy the whole project to both nodes, they run separately. In one node, I make a transaction, I can see it on that node. However, if I login with the same account in second node, it is not there. It is like they run like separate servers. I opened 7874,7875,7876 inboud outbound ports on aws, waited several hours, still no connection.

Connection problem solved. It was a port issue. But now not forging :) throwing the exception in first comment.

asimsinan commented 6 years ago

All solved. Forging problem was related to genesisParameters file. It is related to epochBeginning

@asimsinan I am facing with same forging issue. What should be genesisPublicKey and epochBeginning in genesisParameters.json file under template/config/data ? can you explain in details?
