setting up message relay and update cache

Question

hi all, 
 i have read the "setting up sophos relay and update cache" here 
 https://support.sophos.com/support/s/article/KB-000035498?language=en_US 
 couple of questions - 
 on the sophos central portal it says this 
 Update Cache and Message Relay Status 
 
 Cache Status 
 Active

Last Cache Update 
 a year ago

Using Cache 
 
 No devices

Message Relay Status 
 Active

Using Relay 
 
 13 Devices

Product Update Source 
 lon-d-sopr

Sophos Central Messaging 
 lon-d-sopr

so im using this for the message relay and update cache and devices are using this as a relay (a few so theres a problem) but the cache devices are not 
 
 on the machine thats running the update cache and message relay, should i add another host entry ie 
 
 ip-of-the-server dns-name-of-the-server 
 
 also i get "last cache update a year ago" i have checked and the date and time are correct 
 
 i get this error on sophos central 
 
 Failed to install SOPHOSCLEANM64: general error.

Hi Sophos User1175 , 
 Thanks for reaching out. 
 If it has been two years since the update cache last updated, uninstalling and re-installing may be a better idea. If Sophos Clean is having issues installing, this may be related to why the update cache also fails to update. 
 If you find that the same issue returns after a full re-install, please share the installation logs for Sophos Clean from the C:\Windows\Temp directory. 
 You can also choose to remove/add the Update Cache component individually from devices by navigating to the "Server Settings > Manage Update Caches and Message Relays" menu.
