--- End of inner exception stack trace ---

When this error occurs, the PC that vMix is installed on is completely unreachable from our internal network until after a full reboot of the PC. Other PC's however, have no issue connecting to our RTMP service provider or anywhere else for that matter. We can run other livestream software packages from this same hardware over the same network and to the same RTMP destination with no issues. We like the vMix GUI better than others, but will not be able to continue a subscription unless this issue is solved.

Also - there are no logs generated in Windows Event Manager when this happens - only after the fact when other services are unable to connect to anything.

Please let me know what other information you need to help us bring this to a resolution. If there are some settings on vMix that we have misconfigured, that's fine - we just need to know how to fix it.

Thanks!

-Jason

Hi,
I am of no kind of an expert, but I would try some USB3 Network adapter as a first thing (to eliminate any motherboard/integrated NIC related problem). If I saw right, you are not using Nvidia? Can you turn off hardware coding for streaming?

Those would be my self diagnosing steps, until experts give you some better advice/solution.

Is the NIC actually using a Gigabyte driver? I would update the driver from the OEM (Intel, Broadcom, etc.) because that's easy to do. Is the lockup intermittent or can you replicate on demand? This may be a symptom and not the cause. I'm wondering about the AMD cards too. Could be happening when encoding starts.
