I for some reason thought your utility forced it to your pool/wallet. So this is an issue for anyone not just me with an external miner client.
Program is only forcing mining to your wallet, not redirecting pools. This is mostly issue when you use -allcoins / -allpools or mine Ethereum forks and devfee switch pools. Check if there are these parameters and do you really need them. I am mining ethereum solo mode on ethermine, devfee connects to exactly same server (eu2.ethermine.org) never noticed it switch server. Experimental version is meant to redirect all connections to your pool.
No I don't use any of those and only mine Eth solo on US2.Ethermine, thats whats odd. I just did a scan thru the last week of logs and its only 4 pool variations total that are used. I'm about to set the experimental version up now redirecting them to my pool.
