Looks like all fine. But try to add to yup.conf:
masternodeaddr=94.176.233.84:1237
externalip=94.176.233.84
I've done that, but it hasn't helped. As I updated above, I think it is a coding error that I'll need the dev to fix, unfortunately.
My masternodes also don't started from GUI Windows wallet.
Try to start it from console:
yup-cli.exe startmasternode alias 0 your_alias_here
