StackExchange.Redis crashing .NET webapi


I have create a new .Net core 3.1 web api, that has no other dependencies except StackExchange.Redis.

In StartUp.cs, I am setting up the connection as

public static ConnectionMultiplexer redis;
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) {
            redis = ConnectionMultiplexer.Connect("localhost"); ...

and then later setting up a key as

string value = "run at " + DateTime.Now.ToString();
IDatabase db = Startup.redis.GetDatabase();
db.StringSet("test_key", value, new System.TimeSpan(3, 0, 0));

This works fine in my development environment, but in the production environment it crashes. I get the following error

Faulting application name: w3wp.exe, version: 10.0.14393.0, time stamp: 0x57899135

Redis is working fine in production and development environment.
