this is just a conflict with the png format and the gui wallet..nothing to do with the network
you should look at the point you generated a stake but not accepted and find this in the log
and also i found this on the nevacoin thread which is one of the oldest blake2s
killdemon, make sure Nevacoin's ports are port forwarded, and in the settings enable UPnP. Then send all your coins to one of your addresses.
Also if you are in the US, staking is much harder and 90% of staked blocks are orphaned. I run a second node in EU to avoid this. Btw, are you mining with a high end Nvidia GPU or bought an AMD miner? Saw you on suprnova.
are you guys maybe from the us?
Interesting, I'm from the US and having issues..
Edit: I have orphaning for a long period of time now, 6 hours or so? I even did a clean install of the QT on 3 of my rigs, all orphans. About every 30 seconds, I'll show "Generated but not accepted."
do you have access to an europe vps server and try with this?
i just watched a littlebit and it seems this problem is a user problem..not network..
if you found a pos block and someone else also found a pos block in the sametime but a milisecond faster because of the better connection to the network,the other user will overwrite your blockhash and this is why the blocks are generated but not accepted.the other user got the block you should get because his connection was better than yours
some orphans just normal but that many seems to be a connection issue and everything you can do to improve is forward the port in the router and configure the firewall.
if you own some vps server in eu range just test it there if this looks better
