I have been experiencing this near constantly as of late. I always double check to make sure VRChat isn't down, I run an internet speed test, and it usually says my connection is very fast, and my SDK is updated to most recent version. Tried on both wired ethernet connection and wireless with no perceivable difference between the two. The only connectivity issues I seem to be having are with my SDK, everything else internet based works flawlessly. The only time I seem to have momentary luck in being able to upload is when I restart my router; does that point to any specific issue?
Is this even the right place for this? Let me know. Thanks
