vCenter HTTP request for datastore access returns '404 Not Found'

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• Datastore(s) and contents are accessible from vCenter and the command-line.
• Datastore(s) aren't accessible from https://server/folder[[/ path]?dcPath= path[&dsName= name]] when the server is vCenter
• Datastore(s) may be accessible when connecting to https://FQDN-or-IP-of-ESXi/folder
  
• Third party solutions, ex. backups, that connect to vCenter and require datastore access are failing to establish that connection.

Environment

VMware vCenter Server 7.0.x

Cause

A missing entry in the reverse HTTP proxy configuration file of the vCenter server.

Resolution

1. Open a SSH session to VCSA.
2. Navigate to /etc/vmware-rhttpproxy/endpoints.conf.d
3. Create a backup of vpxd.conf.
4. Add the following lines to vpxd.conf if it was missing them:

   • /    namedpipe    /var/run/vmware/vpxd-webserver-pipe    redirect    allow
     /Query    found    8080    allow    reject
     /pcnotification    local    9232    reject    allow
     /ui    local    8080    redirect    allow
     /vsanHealth    namedpipe    /var/tmp/vsan-sdk-pipe    redirect    allow
     /vsphere-client    permanent    9443    reject    allow
     /vws    found    8080    allow    allow

5. Restart the the vmware-rhttpproxy service after saving the changes:
   • service-control --stop vmware-rhttpproxy
   • service-control --start vmware-rhttpproxy
6. Go to https://FQDN-or-IP-of-vCenter/folder, and you will be able to access it:
