Look like wallet issue, have you run it as a server (B coin)? Or may those port already used, check it. Have you tried with BFGminer? I have the same issue before (a long time ago 
), the same error message as yours with cgmine but run smoothly with BFGmine.
thk you ), the same error message as yours with cgmine but run smoothly with BFGmine.I tested it.
The same question.
have you tried coin B with some of the cgminer --help options like "--no-getwork, --no-stratum, --no-longpoll" ? try with those flags, some old scrypt coins and coins in general have this needed, but i think it was phased out in most new miners with stratum
ive had this problem before, i cant remember if those flags or the "--coinbase-address=" fixed it tho
try tht one too Good luck!
Used these.
Maybe 3.7.2cgminer doesn't support.
