Hi, I’ve seen a discussion about this subject before; however, I’ve been having an issue getting my Gateway Control Utility on Ignition version 7.9.14 to connect. It remains to say “Version Unknown”. I had this problem yesterday morning, I called tech support and we figured that we would reinstall the program to see if it would work, and then it did work after. However, it happened again after I was done at the end of the day yesterday evening. I turned everything off and restarted my computer and I tried to start the GCU and it wouldn’t connect, and it said “version unavailable”. After trying so many times over the course of maybe 30 minutes, it finally eventually connected. Today, I started my day with the exact same problem, it has taken yet another 30+ minutes or so to finally connect (literally as I was finishing typing this). I am wondering if there is any way to fix this problem or what might be the exact cause of this? Here is some of what is written in the wrapper.log for example… INFO | jvm 1 | 2020/06/11 09:34:38 | E [d.dnp3] [16:34:38]: Error synchronizing device: device-name=RTAC\_DNP3 INFO | jvm 1 | 2020/06/11 09:34:38 | java.util.concurrent.CompletionException: io.netty.channel.ConnectTimeoutException: connection timed out: /10.100.21.25:20000 INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.encodeThrowable(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.completeThrowable(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.uniCompose(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture$UniCompose.tryFire(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.postComplete(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.completeExceptionally(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at com.inductiveautomation.dnp3.master.Dnp3Master.lambda$writeToChannel$36(Dnp3Master.java:1105) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.uniWhenComplete(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture$UniWhenComplete.tryFire(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.postComplete(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.completeExceptionally(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at com.digitalpetri.netty.fsm.util.CompletionBuilders$AsyncCompletionBuilder.lambda$with$0(CompletionBuilders.java:97) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture.uniWhenComplete(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture$UniWhenComplete.tryFire(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.CompletableFuture$Completion.run(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | at java.lang.Thread.run(Unknown Source) INFO | jvm 1 | 2020/06/11 09:34:38 | Caused by: io.netty.channel.ConnectTimeoutException: connection timed out: /10.100.21.25:20000 INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe$1.run(AbstractNioChannel.java:267) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.util.concurrent.PromiseTask$RunnableAdapter.call(PromiseTask.java:38) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.util.concurrent.ScheduledFutureTask.run(ScheduledFutureTask.java:127) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:404) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:495) INFO | jvm 1 | 2020/06/11 09:34:38 | at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:905)
