Hi Jean-Serge,Thanks a lot for your answer !LibreOffice is installed on
both servers and ports 8101-8110 are allowed, both of them are in the
same VLAN and there is no firewall between them. The url is also
reachable from the applicative server.I also tried to remove the
environnement variable but it is the same ...All of
pdf/LibreOffice/excel are done through LibreOffice on applicative server
right ? If yes, i don't understand why only Excel export is broken
?Thanks anyway for you help ! Regard...
