An application can't be updated and the errors.log in the JExpress subdirectory of the installation directory reports the error: Unknown host (DNS Error).

If you are confident that the host included in the log is valid and DNS lookup is configured properly, then you should create the diagnostic logs named: webfile.log, webhttp.log, and httptokens.log in the JExpress subdirectory of the installation directory. Review of these logs may reveal more information about the error.
