Symptoms: Error code 0x8004C59 during synchronization, especially with SSL/TLS 1.3-only servers. Root Cause: Version 4.5.59 was compiled before widespread TLS 1.3 adoption. It defaults to TLS 1.2 or older. Fix: Downgrade your CardDAV server’s minimum TLS version to 1.2, or install a compatibility shim that proxies requests from 4.5.59 to your modern server. Alternatively, backport OpenSSL 1.1.1 libraries (provided you recompile from source).
