After adding in one server as the DC, I can adjust the ram, however after adding the 2nd server to the cluster I get an error when adjusting the size

What is the difference between these commands?

Are the both needed?

Update-SPDistributedCacheSize

Set-CacheHostConfig -CacheSize

Commands and Error below

Add-SPDistributedCacheServiceInstance

Use-CacheCluster Get-AFCacheHostConfiguration -ComputerName ComputerName -CachePort "22233"

Update-SPDistributedCacheSize -CacheSizeInMB CacheSize

Set-CacheHostConfig -CacheSize  -HostName YourHostSharePoint -CachePort 22233

Update-SPDistributedCacheSize :
ErrorCode<ERRCAdmin010>:SubStatus<ES0001>:Specified host is not present in
cluster.
