Building a Custom GPT and users cant use it

Hi! I built a GPT in chatGPT for my college course. I use it as a chat bot for students. Here is my issue

  • I test it out, and it works on my end
  • Once is share the link , and make it with anyone is able to use the link, the model wont function. Sometimes it may work for a second, but then it will display an error message of “Not Found, Try again”

Can someone give me guidance? I am unsure what to do.

Again, on my end its fully functioning. For the public, it is not functioning.

Oh, i even built a simple agent, and it still wont let users use it. Maybe once. Thats it.

What am i missing
