Cachehostinfo is null - Error in WFE01 while configuring Distributed Cache in my multi server Prod.Farm

1st run this script to clear all the running instances of the DC

$instanceName ="SPDistributedCacheService Name=AppFabricCachingService"  
$serviceInstance = Get-SPServiceInstance | ? {($_.service.tostring()) -eq $instanceName -and ($_.server.name) -eq $env:computername} 

If($serviceInstance -ne $null){ $serviceInstance.Delete()}

Now run this command and it should not show any thing

Get-SPServiceInstance | ? {($_.service.tostring()) -eq "SPDistributedCacheService Name=AppFabricCachingService"} | select Server, Status

Now make sure that appfabric service is stoped and start type disabled. Check it from services console.

Finally Run the

Add-SPDistributedCacheServiceInstance

Wait for minutes now check the status again.

Use-CacheCluster 
Get-CacheHost

Update:

If above script is giving you the error of null valued expression you can use the modified commands as below and it works successfully:

$serviceInstance = Get-SPServiceInstance | Where-Object {
    $_.TypeName -like "*Distributed Cache*"}

if ($serviceInstance -ne $null) {
    $serviceInstance.Delete()
} else {
    Write-Host "No Distributed Cache service instance found on this server."
}

After this, run:

Add-SPDistributedCacheSericeInstance

Wait for 2-3 minutes.

Here we go and the service has been started successfully.
