The actual SQLSTATE here is k0k13; the extra zero in the string is really an ASCII NULL.
This error typically indicates a mismatch between the -S and/or -H arguments used to start the target Progress instance (which can be seen in the Progress server's databasename.lg file) and those used in the DSN (Options field) and/or Agent setup (ConnectOptions keyword).
Resolution is just correction of the DSN or Agent setup arguments.
