Update : We tried to configure one more frontend sharing same assetstore, database, and Solr.
What I done:
1. Update dspace.ui.url details in local.cfg of original server ,
2. I installed frontend in new server and add rest url in config.prod.yml in new server
by above settings, frontend with all data will be visible but
admin login is not working. It throws invalid email id and password
error. I also checked dspace.log but it is not showing any error
Can anyone help regarding this
