Hi Dojo,

I’m unable to start DataMiner due to the following error in SLDataMiner.txt:

2026/03/10 18:39:56.920|SLDataMiner|13780|11144|CServiceModule::LaunchDataMiner|INF|-1|Startup Dataminer finished successfully.
2026/03/10 18:39:56.982|SLDataMiner|13780|11144|CServiceModule::RunFunc|CRU|0|Startup DataMiner succeeded in 00h 00m 31s

2026/03/10 18:40:04.091|SLDataMiner|13780|4012|IDataMiner::NotifyDataMiner|ERR|0|Finished [0x00000000000000A5] - NT_WATCHDOG_ELEMENT_STATS by DataMiner with error. (Could not communicate with remote DataMiner (hr = 0x800402B8))

As shown above, the log first indicates a successful startup, but immediately after, we get the adapter error, causing DMA to stop.

I have tried the fix suggested in the docs:
What if I have connection issues after a Failover switch? | DataMiner Docs, but it doesn't resolve the issue.

Additionally, I have:

• Tested different active and persistent routes.

• Added the Network Adapter MAC address to DataMiner.xml.

Unfortunately, none of these steps have worked.

Could someone advise if this issue is familiar, or suggest a way to force DataMiner to bind to the correct NIC?

Thank you in advance.

Kind regards,
Nejra
