After I installed iRedMail, the link for iRedAdmin returns 404 error when access. I'm accessing it using http:
http://[mydomain]/iredadmin/

Error page shows:
404 Not Found
nginx/1.14.2

I then tried using the IP address directly but got the same 404 page:
http://[myIP]/iredadmin/

Any help would be appreciated.

Many Thanks,
Leon
