I'm testing on a server with an already existing certificate from letsencrypt. However, the sample program cannot be run. I am attaching the log.

The library and its functionality is what I need. I would love to resolve any issues.

@yarrou It heavily depends on the configuration of the existing KeyStore - the exception you provide indicates that the Keystore is different. This library in general is not aimed on supporting already existing KeyStores out of the box.
Probably this might be seen as enhancement
