Problem :- When Error 404 occur means page is not available on server / Director.
While troubleshooting we found error code in API response:-
login:5 GET https://203.19.37.222/versa/app/styles/css/error-page.css 404 (Not Found)
Solution :-
Check below Directory files and make sure all the files are present with the same permission
/opt/versa/vnms/apache-tomcat/webapps/versa/dist
& compare all files with local setup.
Upgrading the director to next release or even hotfix release could fix the problem if manually checking the below files doesnot help
admin@Primary-Director:/opt/versa/vnms/apache-tomcat/webapps/versa/dist$ ls -latr
