The mining is going back ok now. Not so much rejected blocks anymore.
On my basic pc with 2 threads i got 56 submitted blocks and 7 rejected over a time of 36hours.
Also the disconnections are gone.
Hope at others it is going well now?
I just restarted my miner to check this out I had over 600 rejected blocks. Restarting resets the counter. I hope I get much less rejected blocks.
