Error code 408 \ HTTP TimeoutException

Recently, sometimes when I use eikon.get_data(), it will occur 408 error, and the error kept coming up for the next 30 mins. Then suddenly it can works well again to get the data I want. I want to know why and how can this problem be sovled.

The error show below:

Hi @kathy.ky.ching

It is an HTTP request timeout. As much as I know timeout in the API is around 15 seconds. If Eikon doesn't respond to the ticket request within this timeout, it will throw this error.

                
                 EikonError: Error code 408 | HTTP TimeoutException: .

you can try to change the timeout value by calling the following method.

                
                 ek.set_timeout(50)

If it doesn't help, you may try to reduce the number of requested items or reduce the time range when requesting data.

I hope this will help.

Best regards,

Haykaz

Hi, I already set the timeout value to 100 before, and sometimes I just ask for one RIC for CF_ASK data which has very just one row data, and still this error occurred. Could there be other reasons for this? Cause I set up automatic data extraction at 12 pm everyday. And this error often occurs which is very troublesome. Thank you

Hi @kathy.ky.ching ,

Another thing I can suggest is wrapping the API request in try except statement and retrying a couple of times. This may help avoid temporary sever overloads.

max_retries = 3
retries = 0
while retries<max_retries: 
    try:
        data_root_1, err = ek.get_data("0#SGXIOS62:", ['CF_NAME'], field_name = True) 
        break
    except Exception as e: 
        print(retries, e)
        retries +=1
        #time.sleep(5)
        continue
data_root_1

Best regards,

Haykaz
