I have had this happen randomly; even on my AppleTV. Sometimes it is just a Netflix CDN error. Sometimes it’s the “stuck in the mud” error where clearing the temp/cache folders, then having to log-back in, might fix it.
Also, usually logging into the desktop app for Netflix seems to work better to “bless” the IP you’re using vs Chrome web browser, but that’s me here in US, no VPN, GoogleDNS.
