সমস্যা আছে nginx। এটি ক্লায়েন্ট ডাউনলোড শেষ হওয়ার আগে সংযোগ বন্ধ করে দেয়। এটা দেখতে অনেকটা:

এই কারণেই এই ছবিটি ব্রাউজারে পুরো আকারে আঁকতে পারে না। আমি এর একমাত্র মাথা দেখতে পাচ্ছি।
এনগিনেক্স ফ্রন্ট-এন্ড এবং অ্যাপাচি ব্যাক-এন্ড হিসাবে কনফিগার করা হয়েছে। অ্যাপাচে সরাসরি লিঙ্কটি ভাল কাজ করে, তাই এনজিনেক্সে সমস্যা আছে। আমি কি সঠিক?
nginx কনফিগারেশন:

এই সমস্যাটি সমাধান করার জন্য আমার কোথায় খনন করা উচিত?
হ্যাঁ, কিছুই পরিবর্তিত হয়নি।
