It sounds like you are using a VPN when using the Geo-Filter which is likely causing the issue and blocking your own IP address. The Geo-Filter doesn't have the ability to block your own IP address in normal use. Not many people have had this issue which certainly lends credence to the VPN being the cause. Your account was only created in 2017 so what are the accounts that you reported these IDs on and also please provide them here.
Please disable the Geo-Filter and try again. PSN is also having issues right now: https://status.playstation.com
I have no VPN on that service. The service for the Ps4s and the one device that controls the netduma is on it's own network with a totally different provider.
Also, this is since 2015, so PSN has had issues since then? Only to my IP? and only when the geo-filter is enabled? Come on man.
