It worked fine for months and now regularly throws “SSL received a record that exceeded the maximum permissible length.” errors even though I’ve made no changes. Domain: jaredneedsfood.xyz Error occurs on load. Vercel dashboard shows no indication of domain, DNS, or SSL misconfiguration. SSL Checker finds no problems with the ssl on this domain.   I have removed the custom domain, waited an hour, updated by source repo and redeployed to no avail. Can a Vercel team member manually purge the Edge Cache and re-check the routing configuration for jaredneedsfood.xyz? The app runs fine at https://grocery-list-psi-henna.vercel.app/ Jacob Paris (@jacobparis) · 2025-12-03 This error is usually caused by your network sending HTTP traffic to an HTTPS site - do you get the error on your other devices? other wifi/mobile data? - do you use any corporate proxy or VPN? - do you have any antivirus enabled? The certificates all appear to be in order and fully propagated Ifotn (@ifotn) · 2025-12-03 It appears to happen on 2 different wifi networks on multiple devices. If I use mobile data or a vpn it works.
