Hi,

I know this problem has been discussed more than one time but this couldn't be a CPU or Network problem, why?
Just because this log below, is a stream to Microsoft Azure, this has been created from a streaming platform for my final customer. I'm a video technician and my job is to stream to this rtmp link. After many attempts to streaming with v-mix without success, i've tried using OBS, and it works, but i can't use that beacause i have setted audio bus and Vmix Call for live translation. So at this point i thought v-mix was the problem, but just to be sure, i've created a free personal account to Azure and created a new live rtmp to do my test. Now streaming through vmix toward my rtmp works with no problem, but if i use their link (streaming platform) it gives me the problem in the log below.

Here, my situation:

Streaming setting are the same to both rtmp links (in slot 2 i've checked "Use Stream 1 Quality")
Dell G5, I7 9850H, 16GB DDR4, RTX 2060, NVme 500GB, Windows 10. The tests are done in the same moment with the same lan (non right at the same time otherwise the CPU would be overloaded). Even if it seems to work from log at the beginning, checking on their prewiev link, i cannot see nothing with vmix, with OBS no problem.

Can someone help me?
