Unable to upload videos

I have a Pro subscription. I haven't had any issues uploading video content in the past. Suddenly, the last two days, I haven't been able to successfully post a video. It will upload to 60-100%, then flash a failure message. I haven't changed any of my browser settings. After many failed attempts, I cleared my browsers cache, history, and cookies, then tried again with a fresh browser. The same thing happens. Both on Edge and Firefox. My internet connection runs smooth. SL, games, Hulu, YouTube, and Netflix don't have any problems. I'm not very tech savvy.
