API error on GET

[emerikaji]

I've been trying to get the API working for some time now, to use the /ip route in my Go code. While I did manage to get it working for some time, it suddenly started to refuse my requests, responding with a 401: "You must login first".

I don't understand why this is the case, as my API authorization is still perfectly valid, and I have checked that the ovh.Client properly got all the information from the ovh.conf file- So what else is there to do to authentify?

For additionnal information, here is the code I am using to initialize and request on the API:

client, err := ovh.NewEndpointClient("ovh-eu")
if err != nil {
    return err
}
var res = make([]string, 0)
if err = checker.client.Get("/ip", &res); err != nil {
    return err
}
fmt.Println(res)

I did try using Ping(), just in case the problem came from reaching the API, but it didn't return any errors. Is it a problem on my end?
Thank you.
