Macbook OS Version: macOS 14.7.3 (23H417) Mobile OS: iOS Mobile OS Version: iOS 18.6.2 Mobile Manufacturer: Apple Mobile Model: iPhone 12 Pro Max Page Type: vue vue Version: vue2 Packaging Method: Cloud Packaging Project Creation Method: HBuilderX Steps: The backend server is deployed on AWS in Japan with a Japanese IP. Packaging the APP in HBuilderX and publishing it to the Apple App Store were both successful. In a subsequent version, we planned to add a push notification feature and selected uniPush V2. Due to the separation of frontend and backend, the frontend APP implements functions such as registration, login, password change, page content display, and product lists through the server's RESTful APIs. Test colleagues reported that the APP could not load pages when used in Japan; however, it worked normally in China. In China: Pinging the server IP and domain from a MacBook was successful. Testing the API with Postman on a MacBook was successful. In Japan: Pinging the server IP and domain from a MacBook was successful. Testing the API with Postman on a MacBook failed with the error: HandshakeException: Connection terminated during handshake This appears to be an SSL communication failure. We tested the SSL certificate using www.ssllabs.com/ssltest and received an A+ rating. The certificate should not be an issue. we deselected uniPush V2, repackaged the APP, and uploaded it to TestFlight. The result remained the same: the APP content failed to load in Japan, while it worked normally in China. Expected Result: Access to the Japanese server APIs should work normally both in China and Japan. Actual Result: The APP content fails to load when used in Japan, but works normally in China.
