webmin---Failed to bind to 10000

[007123456]

I tried to create a new pem file for a new https cert
I changwed the host name and number
of bits from 512 to 2048
it gave a pem file with ssl cert and prive key but when I viewed the miniserver pem file
it seems to be the old one which had a diffrent host name and the bits were set to 512 (or not the same as webmin generated in the creation
of the new pem file.
I was wondering how to correct this problem.
