Hotel or airport Wi-Fi can appear connected while requiring a portal login. Do not solve that condition by disabling certificate checks.
Evaluation approach
Explain connectivity failures and support the system's network sign-in flow. Do not continue sensitive requests over unverified connections.
Application example
After network login, retry the original operation safely without applying it twice.
Limits and considerations
Network reachability differs from reaching the service through a trusted connection.
Showing the right error
Distinguish required network login from an account block. Show an actionable issue without directing users to enter application credentials into an unexpected network page.
Checks and decisions
- Test portal networks
- Preserve TLS checks
- Manage retries safely
