 - DNS resolves Power Platform endpoints correctly.
 - Allowlist rules cover dynamic host names and subdomains. Power Platform requests can use long, environment-specific host names under service domains instead of a single fixed host. A rule that allows only a previously observed subdomain can fail at the next routing change, even though no app logic changed.
 - CORS headers returned by Power Platform are preserved end-to-end. Header rewrite or removal can cause browser-level failures (including HTTP status `0`), even if endpoint allow-listing is otherwise correct.
-- Inspection devices support larger DNS responses and EDNS behavior. This is especially important if failures are concentrated by region or office location.
+- Inspection devices support larger DNS responses and EDNS behavior. This condition is especially important if failures are concentrated by region or office location.
 - Secure all allowlist Power Platform host names in web gateways (Zscaler, Netskope, or similar), and protect them from SSL/TLS inspection. SSL inspection is a frequent root cause of HTTP `0` responses and unexpected `403` or `502` errors. The inspection device can break long-lived or chunked connections that the connector runtime relies on. It can also return its own block page if a policy match occurs.

 - Use the Power Apps Live Monitor tool to verify whether the failure is consistent across requests or limited to specific connectors.
 - Review HAR entries for proxy-identifying headers such as `Via`.
 - Look for protocol downgrade patterns, such as `HTTP/1.1` responses where you expect modern `HTTP/2`. Connector traffic should use modern HTTP. Therefore, repeated downgrades often indicate intermediary inspection or proxy fallback, and they can affect reliability and performance.
