I can't upload avatar

Starting August 26th, when uploading Avatar, it will report an error at the “Uploading file” stage. Reinstalling Unity does not solve the problem. Some of the more concerning errors are “PutMultipartDataToURL:https://s3.amazonaws.com/files.vrchat.cloud/… - Connection Timed Out!” and “… .W [HTTPRequest]: Null/empty value for header: Content-Type
UnityEngine.Debug:LogWarning (object)”
The help.vrchat.com webpage automatically refreshes the page after clicking login, and the progress of the requested work order cannot be viewed.
