unable to access the web GUI

Hi guys
I can not access OMV from the webgui, the ports do not seem to work
I tried with OMV-FIRSTAID "configure network interface" and "configure web control panel" in both cases I receive this error:

ERROR: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; systemctl restart 'nginx' 2>&1' with exit code '1': Job for nginx.service failed because the control process exited with error code.

I solved :D, I tried again "configure web control panel" by inserting a port other than 443 https and now it works, first I tried with:

omv-mkconf nginx
service nginx start

I do not know if it was this that solved or changed the port https
