Getting null cert and null issuer in OCSPRequest which leads to crash

[Rush]

Version: at least 4.x to 6.1.0
Platform: Linux
Subsystem: tls

server.on('OCSPRequest', function(cert, issuer, cb) {

When I debug the data here, I get cert === null and issuer === null. If I do cb(null, null); then I get a crash:

Error: error:140C6043:SSL routines:SSL_use_certificate:passed a null parameter

Sorry, I don't have a test case and cannot share my letsencrypt certificate here. @indutny - any ideas what's happening or if the problem is somehow on my end?

Thank you for reporting this. Do you use SNI too?

Yes sir

@Rush may I ask you to share your SNICallback with us? How do you create SecureContexts?

@Rush nevermind, this should fix it #6887
