Are you sure about your ETH address?
That looks malformed to me.

There should not be a /3 in that string.

Update: looking at this some more, I don't recall "C=" or in fact that kind of method is being used by Mr Claymore.
Note his syntax is a space and minus to indicate the next parameter, and I don't recall "C" in the documentation, nor the employment of the  =.

I could be wrong though, where did you get that config from?


Ahh ok, sorry, are you meaning your password is actually c=XVG?

That's a cheap hack I guess, kind of bizarre though, as the pool should do that via the address or the port.

Anyway, some things to think about.
Good luck.
