short URL for Self Service portal noted in documentation is not working.

Hi, 

this  doc    https://docs.sophos.com/central/Customer/help/en-us/central/Customer/concepts/DEGroupPolicySettings.html   and our   pre-boot  screen shows   

Don’t have your recovery key? Contact your IT Helpdesk or go to your Self Service Portal:

https://sophos.com/ssp    

but the shortened  link is not working.   

the  regular link appears ok.     https://central.sophos.com/manage/self-service
