Third micro service project example won`t load

I was trying to go to
which is marked as an example for the third challenge and I would not let me in.
The message I receive is “504 Gateway Time-out”
Can you please help me with it?

Hello there,

There is a chance it is related to Glitch being unstable right now:

If you wait a bit, it does come up.

Yeap, I tried it a couple of times. It did not work. I left it and came back and it worked just fine. Thank you for your time.
