share rejection

[otfmining]

I am fairly to this, only about 6 months. I have three mining rigs running now ( 2 with 4 gtx 1070 8 gb gpu, 1 with 4 amd 580 8gb) they are all running just fine. I built 4th rig ( with asrock h110 pro btc+ 13 card) I only have 6 gtx 1070 now on rig but I am trying to set up with only 1 card active at moment. my problem is the rig runs and can connect to ethermine.org but it keeps "rejecting shares" but it says connected. I have been letting it try to authorize shares for 4 days and still nothing. even after about 20 restarts. I directly cut and paste bat files from running rigs so I can not understand why it does not accept shares.
I have increased virt. mem. to 16000mb. I have intel dual core processor , 16gb ram, scandisk 240 gb ssd, 2 evga 850 watt g3. I do not get why it will not accept shares. I do dual mine too if that makes diffence, eth/dcr . DCR says authorization null

Try changing your pool and port number.  I use port 4444 with eu as first server and e us1 as second and it works awesome. 
Look also at slowing down your overclock too as this will reject shares if it is too high.  I have my over clock set at +720 for gtx 1070 cards and it give no lost share and very few stale shares.
