Ассалом алейкум хаммага. Project да jwt қўлланилган. http да security with jwt ишлаб турибди хатосиз.. Проектни серверга деплой қилгандан кейин JWT INVALID SIGNATURE бервотти. Деплой қилингандан кейин хам http ишлавотти. Муаммо нимада эканлигига бош қотган.

REST API sifatida yozilgan proyektda Spring Security ishlatilgan. Authenticaton email+password asosida, Authorization esa JWT (access va refresh token) orqali ishlaydi. 401 error uchun custom AuthenticationEntryPoint yozdim. 403 uchun esa custom AccessDeniedHandler yozdim. Ulardagi logika shunchaki, exception otilganda, custom exception yaratib, uni ExceptionHandler ga berib yuborishdan iborat. Muammo shundaki, Biror bir JWT token talab qiladigan endpointga, invalid/expired/empty access token yuborilsa, EmailPasswordAuthenticationEntryPoint ishga tushib, 401 error qaytadi. (Men bu holatda JWTAccessDeniedHandler ishga tushishini kutgandim, chunki tokenda muammo bor holat hisoblanadi).

EmailPasswordAuthenticationEntryPoint.java
JWTAccessDeniedHandler.java
SecurityConfiguration.java
ApiExceptionHandler.java

Savol: O'zi umuman AuthenticationEntryPoint faqat /login endpointga noto'g'ri email/password yuborilganda ishga tushishi kerak emasmi?

Agar unday bo'lmasa qanday qilib /login da
