This would be the first wallet I need to open a port or do a port forward to in order to stake. That would be a bad program design. Why would I need open incoming ports if there are master nodes? There should be something in the logs if the wallet needed open ports that it doesn't have? I will have a look.
Maybe the developer could provide an updated instruction for staking with the new wallet (I don't even understand the separation of zSUB1X and Sub1x, do I own old Sub1x coins in the new wallet?). In the old wallet it worked out of the box.
Do not have to change any ports.
At the first start I have also not worked staking, then I started to change the config and the wallet did not work at all...
I reinstalled it and nothing changed, just
unblocked it and everything works.
