Hi @George_Gousios ,

Thanks for the message. I’m pleased to see that you were successful with your resubmission.

Unfortunately our FTP server can be slow at connecting when it is in demand. I recommend that you design code that reattempts connection until successful. Something like:

> while True:
> 
> ```
> try:
> 
> forecast_array = forecast_submission.AI_WQ_create_empty_dataarray(aiwq_var,chosen_date,wk_lt,teamname,modelname,password)
> 
> print("Success!")
> 
> break
> 
> except Exception as e:
> 
> print(f"Error: {e}. Retrying...")
> 
> time.sleep(5) # wait a bit before retrying
> 
> ```

Thanks,

Josh
