nginx: [emerg] bind() to yourip:443 failed (98: Address already in use)

If you are facing problems on starting NGINX or CWPSRV

nginx: [emerg] bind() to xxx.yyy.zzz.kkk:443 failed (98: Address already in use)
or
cwpsrv: [emerg] ind() to 0.0.0.0:443 failed (98: Address already in use)

Probably you changed conf files from
/usr/local/cwpsrv

to avoid the warn messages fro nginx starting
like an example
   nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /etc/nginx/conf.d/vhosts/yourwebsite.conf
   
Just in case you change the
line with
ssl               on;
to
listen 443 ssl;

example: the "listen 443 ssl" in /usr/local/cwpsrv/conf.d/api.conf

will cause one of the errors below avoiding one those services to starting

       nginx: [emerg] bind() to xxx.yyy.zzz.ttt:443 failed (98: Address already in use)

       cwpsrv: [emerg] ind() to 0.0.0.0:443 failed (98: Address already in use)
      
      
The solution is simple

edit
/usr/local/cwpsrv/conf.d/api.conf

and comment the "listen 443 ssl"
the resukt will looks like the example below
ssl      on;
#listen 443 ssl;

in the following or der runs:
systemctl restart cwpsrv
systemctl restart nginx
