Error communicating with DirectAdmin server - login failed

Method 1:

Login keys functionality is turned off in DirectAdmin. Make sure that it is enabled in the following files:

1. edit file /usr/local/directadmin/conf/directadmin.conf and make sure that line login_keys=1 is added. Add it if needed and save file;
2. edit file /usr/local/directadmin/data/users/admin/user.conf and make sure that line login_keys=ON is added. Add it if needed and save file.
3. re-install the plugin by this instruction

Open website builder from DirectAdmin and try to publish the website. If it still does not work, then continue to method 2.

Method 2:

Create login key manually:

1. Log in to DirectAdmin admin account
2. Navigate to /CMD_LOGIN_KEYS in your panel (you can enter this URL manually in address bar)
3. Click on "Create new Login Key"
4. Fill in key name: "siteprobuilder", key value: [think of some 16-char code], expires: never, uses: 0, clear key: checked, allow htm: checked, commands: CMD_LOGIN and CMD_PLUGINS.
5. Enter password below and click "Create".
   If this operation succeeds, create a new file if it doesn't exist already:
   /usr/local/directadmin/plugins/siteprobuilder/include/login_key and put there a key value you used in login key creation. Save the file.
   Afterwards, if everything succeeded, publishing to this server should start working.

Method 3:

Make sure that IP of used website builder server is not blacklisted in DirectAdmin. Make sure that IP is not listed in list of blocked IPs in file: /usr/local/directadmin/data/admin/ip_blacklist or /usr/local/directadmin/scripts/custom/all_pre.sh (if exists).
