  • Ensure your Redis server is accessible from Windows Server 2022 where IIS is running. The fact that redis-cli ping works in WSL/Ubuntu does not guarantee that the Windows environment (where your IIS app pool runs) can reach Redis. By default, Redis on WSL or Linux binds to 127.0.0.1 (localhost), which is not accessible from Windows unless you configure it to listen on all interfaces.

  • Update your Redis configuration (/etc/redis/redis.conf or equivalent) to bind to 0.0.0.0 and set protected-mode no (for testing only; use proper security in production). Restart Redis after changes.

  • In your ABP app's appsettings.json, set the Redis connection string to the correct host and port. If Redis is running on WSL, use the WSL IP address (find it with ip addr in Ubuntu) or use localhost if you have configured port forwarding.

    Example:

  "Redis": {
      "Configuration": "localhost:6379"
    }
  

  • If you are using a password, include it:

  "Redis": {
      "Configuration": "localhost:6379,password=yourpassword"
    }
  

  • If you want the app to keep retrying on connection failure, add abortConnect=false to the connection string:

  "Redis": {
      "Configuration": "localhost:6379,abortConnect=false"
    }
  

  • Make sure the Windows firewall allows outbound connections to the Redis port (default 6379).

  • If you are using Docker for Redis, ensure the container port is mapped to the host and accessible from Windows.

  • After updating the configuration, restart your IIS application.

  • For ABP 8.x, the recommended configuration key is Redis:Configuration. You do not need to manually configure StackExchange.Redis in code; ABP will use the configuration automatically.

  • For troubleshooting, try connecting to Redis from Windows using a tool like redis-cli.exe for Windows or a .NET console app using the same connection string.

  hi

  Can you confirm your Redis connection string is correct? Does your Redis server need a password?

  You can check your appsettings.json file.

  Thanks

  Hi,

  auth project application.json file

  "Redis": {
      "Configuration": "127.0.0.1"
    }
  

  i installed redis insight on windows server machine. wsl linux (ubuntu) is on.

  Try Workbench, our advanced CLI. Check out our Quick Guides to learn more about Redis capabilities.

  hi

  Can you try to set AbortOnConnectFail to false?

  Please update your MyBankStoreAuthServerModule file

  Change var connection = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]!); to var connection = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]!, options => options.AbortOnConnectFail = false);

  Also PostConfigure<RedisCacheOptions>

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      PostConfigure<RedisCacheOptions>(options =>
      {
          options.ConfigurationOptions ??= new ConfigurationOptions();
          options.ConfigurationOptions.AbortOnConnectFail = false;
      });
  }
  

  Thanks.

      });
  

  changed >>>

  context.Services.AddSingleton<IDistributedLockProvider>(sp =>

  1. Solution

  • Root cause is networking, not ABP. Your IIS worker (Windows process) is trying to connect to 127.0.0.1:6379 on Windows, but your Redis is running inside WSL. That loopback is not always reachable from Windows, and WSL can recycle/change connectivity. That’s why RedisInsight shows PONG, then later “Could not connect…”.

  • Fix options (pick one):

    • Preferred: Run Redis natively on Windows or in Docker with a host port binding, then point ABP to that host:port. Example appsettings: { "Redis": { "Configuration": "localhost:6379,abortConnect=false" } }
    • Or, expose the WSL Redis to Windows:
      • In WSL redis.conf: bind 0.0.0.0 and set a password; if needed, protected-mode no (only temporarily for testing). Restart Redis.
      • Find WSL IP from Windows: wsl.exe -d Ubuntu ip -4 addr show eth0 (or use wsl hostname -I). Use that IP in appsettings instead of 127.0.0.1: { "Redis": { "Configuration": "WSL_IP:6379,abortConnect=false,password=yourpassword" } }
      • Ensure Windows Firewall allows outbound 6379 to that IP.
      • Note: WSL IP can change after restart; prefer fixed host (Docker or Windows service) for production.

  • Remove custom ConnectionMultiplexer.Connect code and let ABP wire Redis via configuration. In ABP 8.x, using Volo.Abp.Caching.StackExchangeRedis, setting Redis:Configuration is enough for distributed cache and distributed locks. If you need a distributed lock provider, use the same options and reuse the IConnectionMultiplexer singleton instead of creating a new one. Example module: using Microsoft.Extensions.Caching.StackExchangeRedis; using StackExchange.Redis; using Medallion.Threading.Redis;

    [DependsOn(typeof(Volo.Abp.Caching.StackExchangeRedis.AbpCachingStackExchangeRedisModule))] public class MyBankStoreAuthServerModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { PostConfigure<RedisCacheOptions>(options => { options.ConfigurationOptions ??= ConfigurationOptions.Parse(context.Services.GetConfiguration()["Redis:Configuration"]); options.ConfigurationOptions.AbortOnConnectFail = false; });

        context.Services.AddSingleton<IConnectionMultiplexer>(sp =>
        {
            var cfg = sp.GetRequiredService<IConfiguration>()["Redis:Configuration"];
            var opts = ConfigurationOptions.Parse(cfg);
            opts.AbortOnConnectFail = false;
            return ConnectionMultiplexer.Connect(opts);
        });
    
        context.Services.AddSingleton<IDistributedLockProvider>(sp =>
        {
            var mux = sp.GetRequiredService<IConnectionMultiplexer>();
            return new RedisDistributedSynchronizationProvider(mux.GetDatabase());
        });
    }
    

    }

  • If your Redis requires SSL (e.g., Azure), include ssl=True and the password: "Redis": { "Configuration": "mycache.redis.cache.windows.net:6380,password=KEY,ssl=True,abortConnect=false" }

  • Quick health checks from Windows (not WSL):

    • Test TCP: PowerShell: Test-NetConnection -ComputerName <host> -Port 6379
    • Use a Windows redis-cli or a .NET console app with the same connection string as your IIS app.

  • Why AbortOnConnectFail=false didn’t help: It only makes the multiplexer keep retrying; it won’t fix an unreachable endpoint. You must point to a reachable host:port from the IIS worker process.
