Hope somebody can help. Bitrate issue.

[Clrty]

I really hope someone can help me with this issue.
For the past two weeks, I’ve been having a problem with my bitrate dropping in the evenings. Two checks by my ISP didn’t reveal any network issues. My internet connection is generally stable; the problem only occurs with OBS. There is practically no software on the PC running OBS; it is exclusively a streaming PC in a Dual PC setup. There were no issues prior to this. I have been using Twitch’s Enhanced Broadcast for 2K streaming for about a year now.
Wired connection
Router updated
OBS updated
Running as administrator

I am attaching the stream test log file.
The problem starts at roughly the same time every day.

Lots of issues in that log that I'm ignoring, but just focusing on your network issues, head over to the support page for your mobo & download/install the latest network driver available. That should clear up the non-zero errors that your NIC is currently throwing.

Also, notice the missing Keyframes on (3) of your encodes? That most likely is the stale Nvidia driver currently installed or the lame user option in the encode settings or not following Twitch service limits. You'll need to troubleshoot it if it keeps happening.
