Error in downloading version file: -1

My serial monitor shows only the following output: Start ..............Connected to WiFi error in downloading version file:-1 error in downloading version file:-1 error in downloading version file:-1 error in downloading version file:-1 error in downloading version file:-1

Here's my code:

Can you please specify the steps to collect the sha1 certificate?

Could you please help me with the correction of my code?

pull the latest version, i just updated fingerprint for raw.githubusercontent.com, need to add a way to auto update fingerprint after fw is deployed.

Thank you.. could you please explain to me the meaning of "pulling the latest version"

[programmer131]

download updated code from github,

[SudhaMaanasa]

Ok Thank you.. I tried the updated code. But no improvement. the same outcome.

[SudhaMaanasa]

Yes thq it worked.

Hi, check latest version, i've removed fingerprints from code.
