unable to send API request to Solana devnet

Question

I'm doing the following tutorial of creating tokens on Solana.

https://spl.solana.com/token

and it seems that all requests to Solana devnet are failing

$spl-token create-token
Creating token 2rxgzZ1tk692aZJXDz8NhTkVXQWB396Z3L21nTUYWCFi
error sending request for url (https://api.devnet.solana.com/): error trying to connect: invalid certificate: UnknownIssuer

I'm not so much of an expert when it comes to network, but i thought it was permission issue in firewall as I am currently working on this in corporate environment.

but as I tested with telnet, it doens't seem like a firewall issue 147.28.33.107 is an IP address of Solana devenet network.

telnet 147.28.33.107 80 

Answer 1

I have the similar problem but I sorted out by specifying the path to my-keypair.json.
