The Challange method does not redirect to the specified url

Question

I'm making a site with external authorization through VK, I've looked through a lot of examples, but I ran into one problem, in all examples redirection to ExternalLoginCallback happens through Challange method with provider parameters and url, but redirection happens not to specified url, but to signin-vkontakte-token, which is specified in ConfigureServices. What can this be related to?(It doesn't matter if you give me an answer with the specified provider or another one, such as Facebook)

[AllowAnonymous]
public IActionResult ExternalLogin(string provider, string returnUrl)
{
    var redirectUrl = Url.Action(nameof(ExternalLoginCallback), "Home", new { returnUrl });
    var properties = _signInManager.ConfigureExternalAuthenticationProperties(provider, redirectUrl);
    return Challenge(properties, provider);
}

[AllowAnonymous] 
public async Task<IActionResult> ExternalLoginCallback(string returnUrl)
{
    var info = await _signInManager.GetExternalLoginInfoAsync();
    if (info == null)
    {
        return RedirectToAction("Index");
    }

    var result = await _signInManager.ExternalLoginSignInAsync(info.LoginProvider, info.ProviderKey, false, false);
    if (result.Succeeded)
    {
        return RedirectToAction("Index");
    }

    return RedirectToAction("Index");
}
