I'm having the same issue as well, and I'm wondering when Apple will fix it now. I've never come across this mistake before, therefore I'm forced to submit the app right now! Thank you for your kind words. Regards- https://www.iteducationcentre.com/best-personality-development-and-soft-skills-training-courses-in-pune.php

There might be a lot going on here, but in order to attempt to obtain additional information about where the problem is occurring, take the following steps: Check that your server is utilising a TLS server certificate that matches the iOS 13 minimal criteria. In accordance with the error code errSSLClosedNoNotify, the server seems to be terminating the SSL connection as a result of a failure in the TLS handshake negotiation between the server and the client. In most cases, this indicates that a mistake occurred when negotiating one of three things: the version of TLS used in the handshake, the cryptographic techniques used in the handshake, or the validity of certificates transferred during the handshake. There will be a negative effect on this handshake negotiation if you do not take advantage of the improved security requirements in iOS 13. Look into the possibility of having your server team assist you with debug level SSL logs on the server, which would help you locate where the handshake negotiation is failing.
