Deposit not working

I have a DIY exchange setup based on hollaex.

I just made a deposit of 5XLM to an address i generated on the exchange, but its not showing up even though i can see the transaction succeeded on the block explorer

I have used the heck deposit status to check it, and the status check just gives an error

“Request failed with status code 400”

Pls what can i do?
