hello i've recently starting to stream on twitch. during daytime when i stream i have no problem with obs. but in the night during 09.00 pm to 12.00 pm upload usage limits itself between 0 kbps - 2mbps. i've made some search about this issue and i found out my 1935 port is closed. i even called my isp technician to connect my pc. he resetted my modem. and tried to activate my port but it still looks like inactive. is there any way for me to open it? im having symmetric internet 10mbps upload and download.
