As the error say: your credentials don't have access rights. Resolve that and the error will go away.

But sir on local server works fine same credentials

That means something is different on the server. You'll have to figure out what that is.

Check the firewall settings on the server. If firewall logging is enabled (it is not by default), you might also check the log.

However, there may be also other reasons for this error.
