Hi John Fak •,
Welcome to Microsoft Q&A forum.
As I understand, you are facing "Unable to Load Key" issue in Access Keys of your Azure Redis Cache.
This issue looks strange and could be transient portal issue. I would request you to retry using a different browser and afresh if this helps, please let us know the region of the Cache as it might be due to some temporary outage or maintenance.
Also, I recommend you to try using Azure CLI to Get Keys for your cache as below:
az redis list-keys [--ids]
[--name]
[--resource-group]
[--subscription]
Retrieve a Redis cache's access keys.
This operation requires write permission to the cache resource. Reference: https://learn.microsoft.com/en-us/cli/azure/redis?view=azure-cli-latest#az-redis-list-keys
or with REST as below:
Retrieve a Redis cache's access keys. This operation requires write permission to the cache resource.
Let us know the result so that we can further look into the issue.
Thanks
