    the solution ends with the same error:

    this solution is working:

    https://support.plesk.com/hc/en-us/articles/115001211585-Premium-Antivirus-service-fails-to-start-Plesk-authorization-failed-HTTP-request-error

     

    • Add TLSv1 in the ssl_protocols in the /etc/sw-cp-server/conf.d/ssl.conf, e.g:

      ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    • Restart sw-cp-server and drwebd services:

      # service sw-cp-server restart
      # service drwebd start

    None of the solutions on this page work. I have exactly the same error messages as described here and on the alternative suggestion linked here. However, nothing works. Completely uninstalling Plesk Antivirus and reinstalling leads to the same errors. I have searched high and low for a solution. Nothing works...! Any ideas...?

    Hi Maxim

    I have now been able to resolve the issue. I managed to log in via FTP. I then deleted the ssl.conf file, then rebooted the server.

    Upon checking the newly created SSL settings in /etc/sw-cp-server/conf.d/ssl.conf they were exactly the same as the file I deleted. Nothing was different, except it was a new ssl.conf file.

    So, a bit of a mystery, but everything is working OK now.

    service drwebd restart gives me:

     

    Key file: /opt/drweb/drweb32.key - License key file error!

    A path to a valid license key file was not specified.

    Daemon is enabled for protecting 14 e-mail`s:

     

    But reinstalling didn't solve my problem, I do have a valid license and there are no TLS / SSL problems either? Do I have to switch to Kaspersky now?

    Hello @Dennis,

    Could you, please, submit a request to Plesk Technical Support for further investigation: https://support.plesk.com/hc/en-us/requests/new

    You may use Plesk Premium Antivirus license number in the request form.

    @Ivan: I can't submit any request - I can fill out the form, but there is no button to submit it...

    "Submit" button appears after license number and fields marked with "*" are filled in.

    Hello

    Switching the tls version to "Modern" caused this issue.

    Setting back the option to "Intermediate (recommended)" allowed me to restard drweb.

    This occurs under

    • OS: ‪Ubuntu 16.04.6 LTS‬
    • Product: Plesk Obsidian 18.0.23 Update #4

    I have some other servers under Ubuntu 18 that are not concerned by the issue

    Hope this helps

    Hello,

    I'm not able to install Dr.web.

    I receive this error:

    tarting Dr.Web drwebd...

    and then this error:

    @Pigr_46,

    Check whether TLSv1 is enabled for sw-cp-server:

    # plesk bin server_pref --show | grep ssl-protocols

    In case TLSv1 won't be mentioned in the output, enable it using the command below as it's required for Plesk Premium Antivirus:

    # plesk bin server_pref -u -ssl-protocols 'TLSv1 TLSv1.1 TLSv1.2 TLSv1.3'

    After that start the antivirus process again.

    If the issue persists, don't hesitate to contact our Technical Support Team, so they may check the issue in details.

    @everyone,

     

    Please inspect the syslog file before attempting to implement any of the solutions provided here.

    It certainly is not a good idea to mess with SSL config, if that really is not the root cause of the problem.

    In most cases, you will find the following log entries many times in /var/log/syslog :

    drwebd[....]: Key file: /opt/drweb/drweb32.key - Key file was not found! (No such file or directory)
    drwebd[....]: A path to a valid license key file was not specified.
    drwebd[....]: Plesk authorization failed: HTTP request error [35]
    drwebd[....]: Error: Plesk Software not running.

    and in some cases, you will find each of the above mentioned lines logged twice.

    The log entry

    drwebd[....]: Plesk authorization failed: HTTP request error [35]

    is commonly associated with a solution involving messing about with SSL config.

    The log entry

    drwebd[....]: Key file: /opt/drweb/drweb32.key - Key file was not found! (No such file or directory)

    is commonly associated with a solution involving uninstalling and re-installing Plesk Premium Antivirus (DrWeb).

     

    In fact, both solutions are often not really necessary - just re-install the DrWeb license key!

    That is often all that is required to solve the issue.

     

    Please note that (removing and) re-installing Plesk Premium Antivirus (DrWeb), as suggested by this KB article, often will require that you need to re-install the DrWeb license.

     

    Hope the above helps a tiny bit.......
