Due to required infrastructure changes the non-interactive (bot) login endpoint has been updated to the below and this is live:
https://identitysso-cert.betfair.com/api/certlogin

Italy, Spain, Romain and Swedish domains

For customers using .it, .es, .ro and .se domains the new endpoint is now live and available for the following jurisdictions:
Italian Exchange - identitysso-cert.betfair.it
Spanish Exchange - identitysso-cert.betfair.es
Romania - identitysso-cert.betfair.ro
Sweden - identitysso-cert.betfair.se

Update Required Before 22nd January

The previous endpoint (https://identitysso.betfair.com/api/certlogin) will no longer work from 22nd January 2019. Any attempts to use the old endpoint from this date will return the CERT_AUTH_REQUIRED error.

**You must update your code as soon as possible with the new endpoint to avoid any disruption on the 22nd January**

Existing certificates will continue to work with the new endpoint and don't need to be updated.
