This is fixed now. This werk is marked as incompatible, because manual interaction might be needed to overcome the error on a host. You can either install the newly baked agent manually on affected hosts, or prevent the cause that leads to the missing "Content-Lenght" header: An observed cause for the missing header can be an activated transport compression at some point in the infrastructure between Checkmk server and host. To prevent this, you can add the line<br> <tt>SetEnv no-gzip dont-vary</tt><br> at the top of the config file <tt>/etc/apache2/conf-enabled/zzz_omd.conf</tt> on the server running Checkmk, and reload the system apache with <tt>systemctl reload apache</tt>.
