Hi Dojo,

During startup of one of my systems I noticed below NATS errors

2022/01/10 14:54:07.868|SLDataMiner|2632|6376|CElement::PublishElementConfigToNATS|DBG|0|Called publish to NATS for element 6th Floor

Although my system starts up, I have the impression that it takes much longer.
Do these errors affect the startup time? If so, how can I resolve it?

Hi Jens,

It’s critical to make sure your NATS service is running correctly for your system to operate.

Can you go over the troubleshooting suggestions made here to see if that resolves your issue?

Hi Ive, I had a look in the SLCloud xml file and the IP is correct.

Adapting the firewall rules did the trick. Thanks!
