Hi,

Here are more error logs after I activate the debug mode and debug level log:

2020-05-08 06:17:59,190: INFO pgadmin:    Executing the process executor with the arguments: ['python', 'C:\\Program Files (x86)\\pgAdmin 4\\v4\\web\\pgadmin\\misc\\bgprocess\\process_executor.py', 'C:\\Program Files\\PostgreSQL\\12\\bin\\psql.exe', '--host', 'localhost', '--port', '5432', '--username', 'postgres', '--dbname', 'redacted', '--command', 'REFRESH MATERIALIZED VIEW CONCURRENTLY redactedschema.redactedmaterializedview WITH DATA;'] 2020-05-08 06:17:59,206: ERROR    pgadmin:    [WinError 2] The system cannot find the file specified

And for the Access Denied when Backup/Restore Database, I cannot find any entry on the PGAdmin4.log file.

        Hi,

        Recently I've successfully upgraded to PGAdmin v4.21 as
        Server Mode, but I had some problem when do Database
        Backup/Restore from PGAdmin.
        When I try to browse the directory/folder to store my backup
        file, the PGAdmin4 give Access Denied message. I cannot view
        the directory content which I try to save the backup file.

        Is there any config or setup file I missed to configure the
        directory permission on Windows?

        Another problem is after I upgraded to v4.21, I cannot
        refresh my materialized view using the right click context
        menu with error
        *Failed to create materialized view refresh job. [WinError 2]
        The system cannot find the specified file*

        What can I do so I can refresh my materialized view except
        from running it manually in Query Editor?

        FYI: I run the PGAdmin4 on Windows Server 2016 Standard (x64)
        and Apache/2.4.41 (Win64) mod_wsgi/4.7.1 Python/3.8

    Have you changed any config settings related to PATH (DATA_DIR,
    SESSION_DB_PATH etc)?
    On Windows, the DATA_DIR is set to %APPDATA%\pgAdmin by default.
    Reference:
    
https://www.pgadmin.org/docs/pgadmin4/4.21/server_deployment.html#configuration

    Yes, I've already change the *config_local.py* file according to
    my server path. Below are my *config_local.py* file content:

    SERVER_MODE = True

    LOG_FILE = 'C:/WebApps/redacted/logs/pgadmin4.log'
    SQLITE_PATH = 'C:/WebApps/redacted/pgadmin4.db'
    SESSION_DB_PATH = 'C:/WebApps/redacted/sessions/'
    STORAGE_DIR = 'C:/WebApps/redacted/storage/'

    MAIL_SERVER = '127.0.0.1'
    MAIL_PORT = 25
    MAIL_USE_SSL = False
    MAIL_USE_TLS = False
    MAIL_USERNAME = 'redacted'
    MAIL_PASSWORD = 'redacted'
    MAIL_DEBUG = False

    BTW, on the link you gave above there is no mentioning about
    *DATA_DIR *variable on config file...?? Is there something I miss
    about the config?

    For information, the *LOG_FILE *and *SQLITE_PATH *are working
    fine... I can see the log file and view the *pgadmin4.db *file and
    it's content.
    The *SESSION_DB_PATH *and *STORAGE_DIR *are both I check exists
    and inside it some folder are created acording to the account and
    session logged in to PGAdmin4 Server Mode.

Please check the permission of the file/directory you have changed. It should be 0700.

    Surya
