getting timeouts on redis server intermittently.

We recently did a update and get a timeout error it happens every now and then (intermittently) not sure what is causing this.
We had our dev ops check the pc and everything looks fine on the server. we also restart the server and still get this error.

On Portainer we get the follow error:

Start with the timeout details and the linked StackExchange.Redis timeout guidance, then inspect the stack-trace entry points in ConnectionMultiplexer.cs, RedisBase.cs, and RedisDatabase.cs. Reproduce the intermittent GET timeout if possible and use the reported diagnostics to narrow the cause; done means a confirmed cause and a documented fix or actionable reproduction.
