Same here. I'm not receiving any staking rewards. I received a bunch in mid-June that were never minted in the 1.04 version. I upgraded to 1.05, installed bootstrap, am current and no rewards. Very frustrating that the wallet is so bad and never mints the rewards. I have over 500k coins, so not a boatload but enough. I'm due a lot of coins.
Apply the bootstrap guide and seek out for assistance in discord support channels.
Wallet is working just fine.

"validtime" : true,
"haveconnections" : true,
"walletunlocked" : true,
"mintablecoins" : true,
"enoughcoins" : true,

}
It appears like it's working fine but my last staking reward was May 3rd.
Your wallet log might be off.
Did you check blockchain explorer for the staking address to see if it matches with the dates on your wallet log?
To correct stuff, you can do this just in case;
Tools > Wallet Repair then run “Recover Transactions 2”
