thanks master by your help, finally from the file
	
	
	
		Code:
	
	
		/usr/local/lsws/conf/httpd_config.conf
	 
 following yours instructions we take this fragment of code:
	
	
	
		Code:
	
	
		listener SSL {
  address                 *:443
  secure                  1
  keyFile                  /etc/letsencrypt/live/hostname.SLD.TLD/privkey.pem
  certFile                 /etc/letsencrypt/live/hostname.SLD.TLD/fullchain.pem
  certChain               1
  sslProtocol             24
  enableECDHE             1
  renegProtection         1
  sslSessionCache         1
  enableSpdy              15
  enableStapling           1
  ocspRespMaxAge           86400
  map                     SLD.TLD SLD.TLD
}
	 
 and we "repeat" the lines with some changes:
	
	
	
		Code:
	
	
		listener MYAPP {
  map                     SLD.TLD SLD.TLD
  address                 *:8443
  secure                  1
  keyFile                  /etc/letsencrypt/live/hostname.SLD.TLD/privkey.pem
  certFile                 /etc/letsencrypt/live/hostname.SLD.TLD/fullchain.pem
}
	 
 finally we restart VPS and then "oh sorpraise!" now:
	
	
YES LOAD SSL but...
now NOT LOAD MY APP!, load the DEFAULT website 
	
	
on others words, I get SSL but LOST the REAL content...
how we can fix this problem?
thanks again
