Azure WebJobs SDK: QueueTrigger fails to connect to Azure Storage Queue in Fairfax (US Gov) but works for Blob/Table triggers"

[kmittal30]

Azure Function queue trigger fails to connect to Azure Storage Queue in Fairfax (US Gov) cloud, while blob and table triggers work with the same storage account and credentials. Removing the queue trigger resolves the issue.

Note this is happening only in Fairfax cloud. In farifax only issue is coming with queue trigger not timer trigger.
