Fast answer
Sign in through the supported account or device flow. Explain session security, recovery, device enrollment and revocation without exposing account existence or private route details in errors.
Availability and commercial eligibility
Language preference, account country, billing country, service region, payment eligibility and support language are separate values. Show the current result before signup or checkout and never infer commercial availability from the page language alone.
Support and safe diagnostics
Start with the local process, port and scheme. Then check authentication and clock, DNS, UDP/443, TCP/443 fallback, corporate proxy or TLS interception, route ownership and edge readiness. Use oxaa routes list, oxaa diagnose --network and stable error IDs; review diagnostic output before sharing it and remove secrets, bodies and private paths.
What Oxaa is - and is not
Oxaa is development connectivity for a selected local HTTP or HTTPS service while the enrolled device and authenticated route are live. It is not application hosting, a general VPN, a forward proxy, permanent production deployment, raw TCP/UDP tunneling, arbitrary TLS passthrough, a CDN/WAF replacement or a production webhook delivery platform.
