Hi Stackoverflow Team,
We are currently using Redis for session state and cache management along with SignalR, and everything is working fine
because our current Redis server configuration allows connections without a client certificate(ssl=false option working).
However, we now have a new Redis server that requires a client certificate(ssl=true option) for connections. We have not found any way to specify certificate-related information in the web.config under the sessionState/providers node.
Note: we are able connect/read/write to redi cache with c# code and a client certificate(ssl=true option) for cache management,but issue with redis session state management.
We have used below technology & nuget package to implemented it:
1. .Net Framework 4.8
2. ASP.net MVC Version: 5.2.9 with C#
3. StackExchange.Redis Version: 2.6.96
4. Redis Server Version: 7.2.3
5. Microsoft.AspNet.SessionState.SessionStateModule Version: 1.1.0.0
Our web config configuration is as below:
<system.web>
<compilation targetFramework="4.8" />
<httpRuntime enableVersionHeader="false" targetFramework="4.8" maxRequestLength="2097151" executionTimeout="4800" maxQueryStringLength="32767" encoderType="System.Web.Security.AntiXss.AntiXssEncoder" />
<sessionState timeout="60" mode="Custom" customProvider="MySessionStateStore">
<providers>
<add name="MySessionStateStore" type="Microsoft.Web.Redis.RedisSessionStateProvider" host="redis-NNNNN.c264.ap-south-1-1.ec2.redns.redis-cloud.com:NNNNN" sslHost="redis-NNNNN.c264.ap-south-1-1.ec2.redns.redis-cloud.com" accessKey="<redis password>" ssl="true" retryTimeoutInMilliseconds="60000" throwOnError="true" operationTimeoutInMilliseconds="6000" clientCertPfx="Certificate/clientcertificate.pfx" clientCertPassword="<client ceritificate password>" />
</providers>
</sessionState>
</system.web>
Where NNNNN is the SSL port of redis endpoint.
We are facing below error:
"No connection is available to service this operation: EVAL"
Also attached same error screenshot

Any assistance to resolve this issue would be greatly appreciated
We have tried different option for ssl=true for Redis session state management options and as mentioned, we are able to connect/read/write to same redis server with ssl=true option using c# code for our cache management.
