I've tried the fix

https://support.plesk.com/hc/en-us/articles/12377321562391-Unable-to-start-Plesk-Premium-Antivirus-Dr-Web-on-Plesk-server

But the issue keeps on
I've tried the solution I saw in this forum about creating the file /etc/sw-cp-server/conf.d/plesk-drweb-local.conf
server {
listen [::1]:8443 ssl;
listen 127.0.0.1:8443 ssl;
include /etc/sw-cp-server/conf.d/*plesk-drweb-local.ipv6.inc;
ssl_certificate /opt/psa/admin/conf/httpsd.pem;
ssl_certificate_key /opt/psa/admin/conf/httpsd.pem;
ssl_protocols TLSv1 TLSv1.2 TLSv1.3;
ssl_ciphers EECDH+AESGCM+AES128:EECDH+AESGCM+AES256:EECDH+CHACHA20:EDH+AESGCM+AES128:EDH+AESGCM+AES256:EDH+CHACHA20:EECDH+SHA256+AES128:EECDH+SHA384+AES256:EDH+SHA256+AES128:EDH+SHA256+AES256:EECDH+SHA1+AES128:EECDH+SHA1+AES256:EDH+SHA1+AES128:EDH+SHA1+AES256:EECDH+HIGH:EDH+HIGH:AESGCM+AES128:AESGCM+AES256:CHACHA20:SHA256+AES128:SHA256+AES256:SHA1+AES128:SHA1+AES256:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK:!KRB5:!aECDH:!kDHSECLEVEL=0;
include conf.d/*plesk.inc;
include conf.d/*wpb.inc;
}
(in the lastfix, I se folders does not exist, perhaps it's good for old instalations)
No one fixed the problem
I've a Plesk Web Admin Edition
Any idea?
Thanks

Hi, @JuanCar . Is there a license for the Plesk Premium Antivirus extension present on the server? Also, could you please confirm which folders do not exist on the server - /etc/sw-cp-server/conf.d/ssl.conf?

 

[JuanCar]

No I have no a license
Then That's is my mistake. I thought that Plesk Web Admin Editor includes a Dr.Web license.
and the file I connot find is /opt/psa/admin/conf/httpsd.pem (httpsd.pem is in /usr/local/psa/admin/conf/httpsd.pem
Thanks

I tried that solution, but the issue seems to be a misunderstanding on my part. I thought Plesk Web Host Edition included a Dr.Web license, but it seems that's not the case.
