UnableToConnect Azure Cache for Redis

Question

I am trying to store ASP.NET session state in the cache (Azure cache for redis) as mentioned here https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-aspnet-session-state-provider

but, i am receiving below error.

What am I missing here?

Answer 1

I have read the offical doc, and it works for me.

If you want support 6379, you need to set Allow access only via SSL=No.

I also find this offical blogs, I think it useful to you.

  </providers>
</sessionState>

My test step.

Step 1. Add Session["loginTime"] in login method.

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        // This doesn't count login failures towards account lockout
        // To enable password failures to trigger account lockout, change to shouldLockout: true
        var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
        switch (result)
        {
            case SignInStatus.Success:
                Session["loginTime"] = DateTime.Now.ToString();// Add this line
                Session["webapp"] = "mywebapp";// Add this line
                return RedirectToLocal(returnUrl); 
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

Step 2. Connect your redis cache by redsmin. ( https://app.redsmin.com/)

I have register in this website for checking value.

Step 3. Run project.

Step 4. Check key and value in redsmin.
