System.Security.Cryptography.CryptographicException: The key {xxxxxxxx} was not found in the key ring.
Im running asp.net core on a webfarm using redis as dataprotection.
after getting error like this from redis
Timeout performing EVAL, inst: 9, queue: 1448, qu: 0, qs: 1448, qc: 0, wr: 0, wq: 0, in: 65536, ar: 0, clientName: xxxx
i opt in to make redis thread safe using this code
private static readonly Lazy<ConnectionMultiplexer> LazyConnection = new Lazy<ConnectionMultiplexer>(() =>
{
return ConnectionMultiplexer.Connect("xxxxxx,abortConnect=false,syncTimeout=3000");
});
public static ConnectionMultiplexer SafeCoonect
{
get
{
return LazyConnection.Value;
}
}
and initialize it in startup like :
var redis = RedisConnectionManager.SafeCoonect;
services
.AddDataProtection()
.PersistKeysToRedis(redis, "Key");
but now i get new error
The antiforgery token could not be decrypted. ---> System.Security.Cryptography.CryptographicException: The key {xxxxxxx} was not found in the key ring.
I'm also getting this warning :
Error unprotecting the session cookie.
what should i do?
