I'm not sure what legacy has got to do with this?
I brought it up because I don't know what phone you have, what OS it runs or the version...
Nokia hasn't hosted Maps in some time so odc.nokia.com seems outdated to me and I suspect you are using a no longer supported Maps App.
Originally, it started as Navteq and Nokia bought them up in 2008. Nokia also had a proprietary mapping software called Nokia Maps which turned into Ovi Maps, then back to Nokia Maps. The Navteq and Nokia Maps operations were merged in 2011 and turned into HERE Maps in 2012. Nokia then sold all the HERE holdings and data to a consortium of German car makers in 2015.
Legacy has a big part in this. I have no idea which stage of this evolution your device is trying to access, but since Nokia no longer owns or maintains Map Data I feel that your device is reaching out to a service that no longer exists...
Are you suggesting that a "repurposed" website would choose to use a "invalid security certificate"? Why would Nokia/MS do that?
If Nokia repurposed the servers, that site no longer exists and they let the certificate expire. Nokia sold off all of it's phone business and no longer has any obligation to support those phones.
So without knowing your device, OS and version... I don't know where to follow up for you.
