Slow upload speed when using OBS for twitch

also this is using a wired connection on my pc

FYI, to get faster then 940-960Mbps download, you need to use LAN port 4, which has a orange stripe next to it and is 2.5Gbps. Everything else are 1Gbps LAN ports.

As for your problem, when did it start? Around the time of the Hurricane? How does the coax get from the street to the room the modem is in? Any splitters/amps/filters? Have you looked at your gateway's signal levels from Connection > Cox Network in the gateway's UI?

this whole time i was an idiot and didnt plug my ethernet up to right port, you literally upped my download speed to more of what im paying for thank you :), up load improved slightly but no where near what im paying for. 

Problem started: when i started streaming a few weeks back

coax is ran from one side of the home to the other with out a splitter or anything

how would i look at my gateway level on coxs user interface?

Is that when you know the problem started or just when you started testing for the problem? If you know for a fact it started then, what changed? Also, maybe I missed it, but what changed between getting 2Mbps upload and 30? Were the tests taken at the same time? Did you reboot between tests?

As for how to see your signal levels, go to 192.168.0.1 > user:admin password:password > Connection > Cox Network > Scroll down and look at your downstream and upstream levels. Downstream power should be between -5dB and +5dB or as close to 0 as possible. SNR should be above 36. Upstream should be below 50. You should have 2 downstream OFDM channels and 1 upstream OFDMA channel. These are like the express lanes for your traffic. BTW, they should really make a sticky about this.

im using cat 6E and in the correct port

Have you verified your settings for the network? I have an Alienware R16 with a 2.5gbps Killer ethernet port, and the default setting was for 1gbps. I had to manually change the settings. ALSO, my original ethernet cable a Cat 6E was bad, replacing it  and fixing the settings were BOTH required for me to get 2.5 gbps speed from my ethernet. 

Go into network and internet/ethernet can verify the link speed. I am currently on 500 down/50 up, but yes my equipment can handle MUCH faster. Even though - 

I verified my network card in my PC it's a 2.5 GbE internet card. My download isn't the issue. My upload is speedtest shows it's 40 mbps for me. But whenever I'm sending a constant stream for twitch why wouldn't my upload be that. It's why I used OBS provided twitch bandwidth program. It takes the servers they specifically use for hosting and allows me to see what my upload is for streaming.

When you are connected to any server, you are at the mercy of the server as to the actual upload speed. They can and will limit bandwidth based on the number of concurrent connections; however, seeing the variation in the various test sites for upstream makes me think there may be an issue on our end. Please reach out to us on Twitter at CoxHelp, visit us on Facebook at https://www.facebook.com/coxcommunications, or email us at Cox.Help@cox.com so we can investigate this for you. 

If you are getting 40 mbps upload speed then you are fast enough to support 4K streaming. I know it's not the speed you want to see, and there can be a number of reasons why it's at 40, but that speed IS fast enough to support 4K. 

Again, have you tried swapping your ethernet cable? I know you said you are using a 6E, but I have see new cables be bad cables.
