Until recently, I've been happily able to access my NAS via DDSN using a custom subdomain on a domain name I own, which points to the external IP given to me in the Synology DDNS settings E.g. nas.domain.co.uk. However, recently this is has stopped connecting through any means - browser, apps, webdav; the lot.
I can still access the NAS locally on my network and Quickconnect is fine as well. The DDNS settings in the Control Panel all show normal; however, I've tried using the external IP from Synology via my browser and that doesn't work, so I'm assuming the problem is somewhere between that address and my network.
I use Google Wifi and have checked the port forwarding rules, and none has changed. I'm in the UK and have an ISP router (Virgin Media) but it's set to modem mode and just passes signal through to the Google router.
Can anyone suggest where the best place to investigate would be?
