Anyone have experience running ktor-server on Android using sslConnector? Tried to use AndroidKeyStore without luck. (stack trace in thread)

@hhariri @e5l do know at least if this should be possible before we invest too much more time trying to get this working?

[e5l]

Hey, I didn't check netty server on the Android . @cy could you take a look?

[cy]

Looks like it fails due to some key misconfiguration. Need to investigate.

[cy]

Btw, we never tried netty ssl on Android

[cy]

Netty itself should work but need to check requitements

[John O'Reilly]

thanks @cy

[John O'Reilly]

@cy Do you think it would make a difference to use a different engine instead of netty here?

[John O'Reilly]

we tried Jetty but now get

[John O'Reilly]

tried CIO and get

UnsupportedOperationException: HTTPS is not supported

[John O'Reilly]

looks like the LdapName error was caused by certificate config issue ....got passed that and seeing if we can get this working with Jetty

[John O'Reilly]

@cy did you by chance find anything more about this i.e. ability to use Android Keystore when using netty?
