Saber646: > 1. Does my hosting plan support outbound connections to external database servers (not hosted on InfinityFree)? > No. Saber646: > 2. Is the pdo_pgsql / pgsql PHP extension enabled on my account? > No. Saber646: > 3. If outbound external DB connections are blocked by policy, is there any way (even on a paid/premium plan) to allow this? > I’m not completely sure about outbound connections, but premium hosting does support PostgreSQL hosting, which means that the required PHP extensions are available too. Saber646: > I’m hosting a PHP-based REST API on my InfinityFree account Ignoring the Postgres connection issues, this wouldn’t work in the first place. But also here applies: premium hosting is the solution, this is a free hosting only restrictions. Why isn't API access working on my website? Websites and PHP > If you’re trying to use APIs on your InfinityFree website and they’re not working, this is due to our browser security system that’s required on all free hosting accounts. What’s happening? InfinityFree uses a security system that requires JavaScript and cookies to access websites. APIs and automated tools typically can’t execute JavaScript or store cookies, so they get blocked by the security system. When API clients try to connect, they usually receive a “403 Forbidden” error or a HTML respo…
