Hi,we ran into the same problem with a clean install of AEM 6.5+SP12. Everything seems correct but the standby seems not to call the primary istance. From the standby or primary log I didn't find anything relevant.Trying a curl to the primary also results in error "io.netty.handler.codec.DecoderException: not an SSL/TLS record" In the meantime I will try with the workaround suggested by @jugs installing oak-segment-tar-1.24.0.jar
