yet when i mine at home, or at the hotel i stay at frequently i don't get these messages
Getting some stale work is normal. This happens when the server sends you new data but you send in work results based on old data at the same time. The work is then rejected. Up to 0.5% of your work being rejected is normal.
So the question is, are you seeing an abnormal ratio of rejected work?
Thanks for your reply
Bitminter client is reading:
Proofs of work accepted by the server: 2113
Proofs of work rejected by the server: 72
at time of writing
so yeah its a little high, but the fact that i see way more rejected when im on my work network than i do on any other network
