Check Doubao's public web path from this network, compare IPv4/IPv6 exits, and review region, ASN, and proxy signals. App, web, and account behavior may use different paths.
Checking
Doubao ships as a website, a desktop client, a mobile app, and a browser extension. This page reflects the browser path only; the clients use their own endpoints.
A loading page means the browser can reach Doubao's public resource. The desktop client and mobile app use separate endpoints, so if only the client fails, start with its version, the local firewall, and proxy settings.
Doubao is operated from mainland China, where direct access is normal. Routing it through an overseas proxy lengthens the path and invites failures, so check whether a proxy rule is capturing its domain by mistake.
Dual-stack access is common on domestic broadband. When the two exits differ in carrier or region, their behavior can differ as well. The page reports each one, and the address family actually in use is the one that matters.
