Matlab Web app Server 2020a

Hallo,

I get errors starting the new Matlab Web App server on a Linux system with console only.

I did the following to install the server:

installer_input.txt:
destinationFolder=/usr/local/Matlab2020a
fileInstallationKey=XXXXX-XXXXX-XXXXX-XXXXX
agreeToLicense=yes
outputFile= /tmp/mathworks_2020a_webapp_install
licensePath= /usr/local/Matlab2020a/license.dat
product.MATLAB_Web_App_Server

to install:

./install -inputFile /usr/local/Matlab2020a/installer_input.txt

I use the local User for starting the Server and Worker with the following Server-setup:

                        port: 9988
                   apps_path: /local/MathWorks/webapps/R2020a/apps
                   logs_path: /local/MathWorks/webapps/R2020a/logs
               logging_level: normal
     log_archive_max_size_mb: 50
        log_rotation_size_mb: 10
                     license: [e-mail]
            maximum_sessions:
session_idle_timeout_minutes: 5
     startup_timeout_seconds: 45
                 ssl_enabled: false
        ssl_certificate_file:
        ssl_private_key_file:

When I start the matlab Web App Server, I get the following Error:
