@praful-vats can you confirm if nsepython is still working?

[reachbharathan]

@TheRealXenoZ are you receiving this error only for specific method, I am receiving the error for all the methods.
can you confirm other methods are working as expected.

[alloc7260]

@reachbharathan @praful-vats some function of nsepython depends on nsepy so if you are using those they will not work

[anil8593]

Changing the URL to the following fixed my problem:

"https://www.nseindia.com/api/equity-stockIndices?index=SECURITIES IN F%26O"

P.S. The url still sometimes fails, add retries and try except in your code should help

[alloc7260]

There is lot's of apis in nse that they use internally.
Each api has it's own use that can be used while in different scenarios.
