Bende de aynı sorun oluştu, cyberpanel kullanıyorum uyarıda php tarafında fsockopen ve gethostbynamel fonksiyonlarının açık olması gerektiğini yazmışlar kontrol ettim sorun yok.
Ek olarak
Tcp bağlantısı yapması gerekiyormuş. Güvenlik duvarı kurallarına baktım ama çözemedim. Eklenti veya sunucu kaynaklı gibi, güncelleme yaptıktan sonra bu uyarı çıkmaya başladı çünkü.
