Delphi 7 (released 2002) and Indy 9 (Internet Direct) were built in an era when SSL/TLS was nascent. Today, connecting to modern APIs (Stripe, AWS, Google) or even standard SMTP/IMAP servers forces these legacy components to negotiate TLS 1.0, 1.1, or 1.2—protocols that did not exist in their original release.

Add runtime logging in Delphi to check the loaded OpenSSL version: Delphi 7 Indy 9 Could Not Load Ssl Library
Some OpenSSL distributions require the Visual C++ Redistributable. Use "Light" versions to avoid this. 4. Why This Happens

// Your code here... end;. If it can't find them, or if the versions are too new, it gives up. Step 1: Get the Right DLLs Indy 9 is quite old, and it is not compatible with modern OpenSSL 1.1.x or 3.x branches. You must use the Find the OpenSSL binaries for version (specifically versions like 0.9.8zb or similar). Ensure you are using
// Attempt to load if not LoadOpenSSLLibrary then raise Exception.Create('Failed to load SSL library from ' + ExePath); end; If you need TLS 1
If you need TLS 1.2 or 1.3 support, note that OpenSSL 1.0.2 supports TLS 1.2 but not TLS 1.3. For TLS 1.3, you genuinely have no choice but to migrate to a modern Delphi version (10.x+ with Indy 10). But if your legacy app needs to connect to an old server (TLS 1.0/1.1), the solution above will keep the lights on for years to come.
