What did you do?

run the commands,
go mod vendor
or
go get -v -x github.com/dgrijalva/jwt-go/@v/v3.2.0+incompatible

What did you expect to see?

(The downloading successful response)

What did you see instead?

go: github.com/dgrijalva/jwt-go@v3.2.0+incompatible: Get "https://proxy.golang.org/github.com/dgrijalva/jwt-go/@v/v3.2.0+incompatible.mod": unexpected EOF

1.14 is no longer supported, does this still happen with a supported release (1.15, 1.16)?
(It is also more likely to a network issue on your end)

I also suspect this may be due to some network issue. However, I could directly open/access the link https://proxy.golang.org/github.com/dgrijalva/jwt-go/@v/v3.2.0+incompatible.mod via browser/using wget in the same environment. Wondering in the backend how the commands "go get"/"go mod" differ from opening the link directly.

I havn't got a chance to switch to 1.15/1.16 to test in the same environment, but definitely will give it a try soon later.

I suspect you have a proxy configuration that wget and your browser understand but that Go does not.

Yes I have a proxy configured for web access. From my IDE (VS Code) it should take the same proxy settings (http_proxy/https_proxy) and I trigger the commands from the IDE only. I am not sure why both ways behave differently.

Could this be a proxy configuration issue? It looks superficially similar to #29809. (See especially #29809 (comment).)

Thanks a lot! After removed the "https://" from the proxy settings, I am able to connect and download. Have a nice day!
