NGINX wont start

I install virtualmin on centos earlier, then replaced apcahe with NGINX, it worked for a while then it seemed to stop and when i restart it this is what i get below. Any ideas why ?

Failed to start service : Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 188.226.142.188:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 188.226.142.188:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 188.226.142.188:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 188.226.142.188:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 188.226.142.188:443 failed (98: Address already in use) nginx: [emerg] still could not bind() [FAILED]
