Redis backplane using connection string doesn't seem to identify the redis endpoints

[efreeman518]

.Net 9, latest C#

Have not determined if this is a bug, but watching the VS debug output with FusionCache configured with Redis backplane using the Redis connection string shows the Redis sdk complaining about no endpoints.

Instead of using a connection string, I tried building StackExchange.Redis.ConfigurationOptions, explicitly defining the 'Endpoints' which seems to be working. Code below.

Researching - I came across this article
https://markmcgookin.com/2020/01/15/azure-redis-cache-no-endpoints-specified-error-in-dotnet-core/

config.GetSection(cacheInstance.RedisConfigurationSection).Bind(redisConfiguration);
var redisConfigurationOptions = new StackExchange.Redis.ConfigurationOptions
{
    EndPoints =
            {
                redisConfiguration.EndpointUrl,
                redisConfiguration.Port
            },
    Password = redisConfiguration.Password,
    Ssl = true,
    AbortOnConnectFail = false,
    ChannelPrefix = new StackExchange.Redis.RedisChannel(cacheInstance.BackplaneChannelName, StackExchange.Redis.RedisChannel.PatternMode.Auto)

};
//var connectionString = config.GetConnectionString(cacheInstance.RedisName);
fcBuilder
    .WithDistributedCache(new RedisCache(new RedisCacheOptions() 
    { 
        //Configuration = connectionString,  
        ConfigurationOptions = redisConfigurationOptions
    }))
    
    .WithBackplane(new RedisBackplane(new RedisBackplaneOptions
    {
        //Configuration = connectionString,
        ConfigurationOptions = redisConfigurationOptions
    }));

public class RedisConfiguration
{
    public string EndpointUrl { get; set; } = null!;
    public string Port { get; set; } = null!;
    public string Password { get; set; } = null!;
}

Mmh, this is really strange: this is the related line, and I normally use Redis via either the connection string or the multiplexer factory.

Can you share the (redacted) connection string you're using?

//Redis Cache ----------------
"Redis1": "xyz.redis.cache.windows.net:6380,password=x..y..z..,ssl=True,abortConnect=False",

no specific endpoints defined in the connection string, I was assuming a default based on the url & port

Ah, it's on Azure: did you allow connections to it? Depending from where you are connectin from, you may need to enable vnets, specific ips, etc.

Also, only the backplane seems not to work or also the distributed cache?

[efreeman518]

Yes Azure, public endpoint so no vnets or ip whitelist configured. Distributed cache seems to work fine, it's only when configuring the backplane the errors occur.

Hi @efreeman518 , any news on this?

[efreeman518]

no updates at the moment, will take some time to research as other tasks are taking priority.
