No connection is available - Azure Cache for Redis

Hello

At most random moment I got error from application :

No connection is available to service this operation: ****; It was not possible to connect to the redis server(s). To create a disconnected multiplexer, disable AbortOnConnectFail. ConnectTimeout; IOCP: (Busy=0,Free=1000,Min=4,Max=1000), WORKER: (Busy=1,Free=32766,Min=4,Max=32767), Local-CPU: unavailable It was not possible to connect to the redis server(s). To create a disconnected multiplexer, disable AbortOnConnectFail. ConnectTimeout.

When I check Azure Cache for Redis, then under OverView - STATUS it is saying - Running - Basic 250 MB. But if I check console and try to ping I get error: Connection Failure: If this issue persists, ensure your computer's firewall and proxy settings allow outbound TCP traffic to port 10225. Using the firewall feature on your cache may also block connections from the console if your IP address has not been whitelisted. There is no IP limitations.

Feels like redis cache is down, but azure shows like everything is fine. Tried to reboot several times. Changed application to use different cache and then everythings works ( so I would exclude application problem )
Any ideas on diagnostics or how to fix this ?

Thank you

    Hi @Anonymous Thank you for posting your Question on Microsoft Q&A.

    Basic SKU cache does not come with high availability. And that status field in portal does not reflect any current availability measurements
    So it can be temporarily unavailable even when it says running in the portal. Please try again and let us know if you are still seeing any error message.

    Regards,

    Hello
    Thank you for the reply.

    It, has been disconnected for 3-4 days now. Only thing I can do is create new cache and delete this one, because it does not seem to start working again ( tried rebooting several times )
