@Jonna, Sasanka Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I understand you are facing exceptions from your application while trying to connect to Azure Redis cache.

From the error message its pretty clear that this is an issue with connectivity. Here are a few action plans to try:

Plan 1: When you use a third-party firewall or proxy in your network, check that the endpoint for Azure Cache for Redis, *.redis.cache.windows.net, is allowed along with the ports 6379 and 6380.

Plan 2:
Could you please try checking the network connectivity ( between your dev machine and the azure redis cache ) ? This can be done by running the telnet client command as shown below:

Try for non-ssl (6379):

telnet sjrediscache.redis.cache.windows.net 6379

Try for SSL (6380):

telnet sjrediscache.redis.cache.windows.net 6380

If the port / connection is not open it will throw an error. If the connectivity is fine, It should show a blank window.

Plan 3: You could try connecting to the Azure Redis cache server using redis cli tool as shown below: **

redis-cli.exe -h yourcachename.redis.cache.windows.net -p 6379 -a YourAccessKey**

If you send PING command, the reply should come as PONG. Then we know connectivity is working fine.

For using rediscli with 6380 port follow this article.

Plan 4: You can navigate to the Azure Redis cache portal and open the console and try the Ping command and wait for the PONG reply.:

Plan 5:
On the Azure Redis cache also confirm if you don't have any Firewall / Vnet configured.

Plan 6:
You can test connectivity using psping command too. Refer this.

Hope this helps.
