issue fetching unimod_tables.xml

[hddesai]

Hello I think there's an issue with fetching this xml file "unimod_tables.xml." Do you think it's due to network/firewall issues? I had our IT look into it but run into the same issue. Should I change the source code to fetch this file locally? Thank you for your help!
