Hello 
Recently we started to have issues with uploading files from our websites to dropbox via http request (php). Right now we can barely upload one or two photos. It now takes far more time to upload even small files and usually we get '504 Gateway Time-out' error. Also this thing started like two weeks ago, previously everything worked fine.
Tried uploading from different devices, browsers, cleached cash and still have this issue.
Have someone come across such issue?
