Problem uploading photos and files on certain apps

[AC Question]

I am trying to upload text (restaurant review) and photos on some apps. It says problem with connection. But the other apps that requires internet connection is running fine. The innternet connection i am using is also stable on other devices other than my Note 4. So what's going on?

Almost anything. Which app? What site? Mobile data or wifi? Which carrier?

Many things could be "going on" - you aren't giving us enough information to even make wild guesses. Have you tried uploading those same files to those same sites with a laptop or desktop?
