Getting error while getting instrument for NSE.

vukumail edited May 2023 in Python client
I fetch instrument list once in 24 hours. But now it is giving this error quite frequently.

Error log

Traceback (most recent call last):

    I am also seeing the same error. It works after retrying 5-6 times. I don't think this is related to rate-limiting at all as in my flow, I do this immediately after user logs in, with a delay of 15 seconds added for good measure.
    It seems to happen more frequently during morning (or at least I am not able to reproduce it at night time).

    Can someone please help?

    Is this still happening? We had informed the team to take a look at this.

    Now it is not happening. Earlier it is used to happen but it was handled by my retry mechanism which tries to call 3 times with a back-off of 5 seconds.

    This time it failed for 15-20 times. I retried by logging in multiple times.
