How to handle “Exception while opening SLNetConnection”?

Solved1.06K views25th August 2022connection SLNet VM

Baptiste Pattyn [SLC] [DevOps Advocate]5.70K 25th August 2022 0 Comments

I am looking to run a DMA on a VM with Virtualbox but when trying to open a connection to the DMA by using Cube or Client Test Tools I get a timout error. When I started looking in the log files I found some errors in SLErrors.txt showing the following exception:

2022/08/25 15:44:16.892|SLAnalytics.txt|SLAnalytics|SLNetConnection.cpp(170): Skyline::DataMiner::Analytics::SLNetConnection::openConnection)|ERR|0|Exception while opening SLNetConnection:

In SLClient.txt I get the following errors:

2022-08-25 15:41:55.745 [33763 Cube (<not authenticated> @ PC) (::1 – <not authenticated>)] [Info] CLOSED (Authentication took too long.)
2022-08-25 15:42:03.506 [5A255 HTML5 App (<not authenticated> @ PC) ( – <not authenticated>)] [Info] CLOSED (Authentication took too long.)

Finally I came upon some logging in SLNET.txt:

2022-08-25 15:45:30.447|72|Destroy|Connection did not authenticate. Computer: PC Application: SLDataMiner.exe
2022-08-25 15:45:30.447|72|GenerateInformationAlarm|Not generating information alarm (no agent up and running): 283/2100000000/64637 [Connection did not authenticate. Computer: PC Application: SLDataMiner.exe ]
2022-08-25 15:45:30.447|72|GenerateInformationAlarm|Not generating information alarm (no agent up and running): 283/2100000000/64505 [SLDataMiner.exe removed because of error: Authentication took too long.]
2022-08-25 15:45:45.581|25|ExecutionContext.RunInternal|Destroying connection 51bc2bd8-7891-4fa6-bf30-605d241c579f (SLNet Test Client): Authentication took too long.

Any help is appreciated.

Hi Baptiste,

Can you check the content of your SLDataMiner.txt log file?
I suspect that this will report a failure on SLNetCom.

If that is the case, you’ll need to verify if the IP address in the following files matches the IP address of your server:

C:\Skyline DataMiner\DMS.xml

C:\Skyline DataMiner\NATS\nats-streaming-server\nats-server.config

Hi Ive, thank you. That was indeed the issue. Note that I also had to change the NATS endpoint in the SLCloud.xml file.
