How To restart Vestacp

[wook1234]

The service Vesta was not able to restart with the following error:
Jun 23 13:48:50 sv.khangvietbook.vn vesta[31370]: nginx: [emerg] bind() to 0.0.0.0:8443 failed (98: Address already in use)

I changed port 8083 to 8443 but now can't access admin page.
I contacted the server provider and submitted a ticket asking them to restart vestacp .
But they return me results like this .
Hope you guys can help me solve the problem and get it back to normal

8443 used already, apache did it first.
