FreeCodeCamp challenge completed and update API returns 500

UPDATE:
app says We cannot reach the server to update your progress.

What can be the issue?

I was submitting the SASS when my progress was not getting saved. this is the screenshot from console

Api fails multiple times even after auto retry

  • modern-challenge-completed
  • update-my-current-challenge

Response
{“type”:“errors”,“message”:“Oops! Something went wrong. Please try again in a moment.”}

Anyone else facing similar issue?

PS- I am continuing this course after a long time. Can that be an issue?
