If you need to update your DirectAdmin license manually, you can do so by running the following commands:
./getLicense.sh 123 1234
123 and 1234 are your Client ID and respectively License ID.
If there are errrors extracting the update.tar.gz file, then run the following to see the errors that show up :
head -n 1 /usr/local/directadmin/conf/license.key
If you have multiple IPs on your device and wget is binding to the incorrect one, you can specify the IP to bind to by adding it as the last argument:
./getLicense.sh 123 1234 126.96.36.199
