Unable to Update Service Account for SharePoint Distributed Cache

I am trying to change the account used for distributed cache from the farm account to a less privileged service account. I perform the following.

Stop-SPDistributedCacheServiceInstance -Graceful -Verbose

$farm = Get-SPFarm
$cacheService = $farm.Services | where {$_.Name -eq "AppFabricCachingService"}
$accnt = Get-SPManagedAccount -Identity 'domain\account'
$cacheService.ProcessIdentity.CurrentIdentityType = "SpecificUser"
$cacheService.ProcessIdentity.ManagedAccount = $accnt
$cacheService.ProcessIdentity.Update()
$cacheService.ProcessIdentity.Deploy()

Get-SPServiceInstance | where typename -like "*cach*" | Start-SPServiceInstance

The account name changes and the AppFabric Caching Service starts.

However, afterwards I cannot connect to the cache cluster anymore.

Use-CacheCluster
Get-CacheClusterHealth
Get-CacheClusterHealth : ErrorCode<ERRCAdmin040>:SubStatus<ES0001>:Failed to connect to hosts in the cluster
At line:1 char:1+ Get-CacheClusterHealth+ ~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : NotSpecified: (:) [Get-AFCacheClusterHealth], DataCacheException+ FullyQualifiedErrorId : Microsoft.ApplicationServer.Caching.DataCacheException,Microsoft.ApplicationServer.Cachi
   ng.Commands.GetAFCacheClusterHealthCommand

Changing back to the farm account allows it to function again.
