Linux command does not run from crontab, but it runs fine from the Linux shell

I set up the following cron job to check every minute if port 8088 is listening. If it isn't, the CLI should write the message Thu Jul 3 12:50:09 UTC 2025 bad to the log file /tmp/crob_log. Here is the cron entry: crontab -e * * * * * root wget http://DB_SERVER_we:8088 ; [ $? -ne 0 ] && echo date bad >> /tmp/crob_log However, the cron job always logs the "bad" message, even though the exit status from wget http://DB_SERVER_we:8088 is 0. When I run the same command manually on the Linux machine, it works fine (no "bad" message), which is the expected behavior. But when it runs from cron, it always logs "bad". So, what's wrong with the command line in the crontab?
