!ALERT Your device is not able to connect with the Customer My Account server since the last 1 days. If the device fails to synchronize for -1 more day(s), it will be deactivated. Please Click Here to synchronize manually.

Can't seem to get rid of this alert, if I click where it says Click Here to synchronize manually it takes me to the Licensing section where I click Synchronize Licenses with Customer My Account button which does successfully synchronize. Shorty after this I then receive an email as below.

Your virtual Sophos appliance has been unable to connect with the Sophos Licensing Server. Failure to connect for few more day(s) may result in deactivation of appliance.

Note: The virtual Sophos appliance requires Internet connectivity to connect with the Sophos Licensing Server.

Virtual Sophos appliance details:
Model No:SFVH
Appliance Key:

Otherwise everything seems to be working fine. If I do nothing I receive the email a couple of times a day.

I'm running Firmware version SFOS 15.01.0 MR-3 but had the same issue with the previous version.
