Dspace Front-End error 500

[prav...@gmail.com]

Hello,

I have a server with Dspace 7.6.1 and i have changed the localhost to internal private ip address at http://10.99.100.10:4000 initially it shows homepage and then the frontend returns a 500, 

The back-end is at http://10.99.100.10:8080/server and everything seems to be fine, as well as the solr at http://10.99.100.10:8983/solr/#/, 

could you help me to solve this problem ?

Thanks and regards,

Pravin

Hi Pravin,

See our "Common Installation Issues" guide as it provides a variety of scenarios (and possible solutions) around when this 500 error may occur:

Simply put, a 500 error in the UI usually means there's a misconfiguration & the frontend (UI) is unable to communicate with the backend (REST API).
