[dspace-community] DSpace 7.3 browsing issue - Java scripts not loading properly

[Thierry RUGWIZANGOGA]

Dear Team, 

Please help and assist to end my nightmare; 

Some of the Users (mostly those joined on the domain) are not able to browse well using any of the browsers (Chrome,Mozilla, Edge, Opera) for both our dspace site or demo7.dspace.org.

Once Logged in, some features seem freezing like Sidebar (and some menus from the freeze sidebar are freezing but others responding),

Below are some additional information;

Dspace error from Development tools (Console) on the Login Page :

Dear All, 

It took quite a while to respond to this but I am glad to let you know that we managed to find out the solution to the root cause which was the Time difference between the Domain Controller and the DSpace server! After adjusting the time to sync with the right NTP Server on the DC the problem got solved.

Thanks and Enjoy Digital World!
