Miner Connection Issues

HIya,

I have all my miners here, and move them from solo on specific coin to Most Profitable from time to time.
From last night its been not letting my miners re-connect. i have had to add backup pools for each of them.

Really keen to get them all working again.
I'm mostly doing Solo BCC & BCO and also a=scrypt Miners L3+

Does anybody have any information of resolution for this?
Thanks for help!

The miners sometimes connect with backup pool.

Pool 1 Primary :
Pwd : c=Bridgecoin m=solo n=s5BC

Pool 2 Secondary :
Pwd : a=scrypt n=s5

Secondary pool seems to connect after some time with promary showing as dead ( It took some hours to re-connect to secondary pool )
I have the issue with BCC and BCO.
Thanks for help! Im keen to rent some miners for a solo play.
Thanks guys!!

Best regards,
Phil D.
