Could you please specify the exact URL that you’ve used that end up generating the above error ?
( i.e. there could several reasons why you’ve received this error message; you haven’t provided much information about your environment, setup, etc. )
the above is just the base address. I’m wondering what the full request URL looks like.
( including the full path ). If Algorand Studio doesn’t provide this option, I would try and install Wireshark and examine all the outgoing HTTP requests to see what request is being made ( it might be an overkill, there could be an internal Algorand Studio feature that would do that - but I’m unfamiliar with it… )
Can you show what the way you created your algod client in Go, replacing the token by xxx?
This error most likely comes from an incorrect URL or incorrect token.
