Unable to access the vCenter landing page for vCSA 6.x/7.0

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• Unable to access the vCenter landing page (https://vcenter.domain.tld/)
• However, the vSphere Client login page (https://vcenter.domain.tld/ui) is accessible
• This issue can be reproduced in different web browsers, clearing cache and/or cookies in the browser does not change the behavior

Environment

VMware vCenter Server 7.0.0

Cause

• This error occurs due to a missing redirect entry for "/" in /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf 

Resolution

To fix this issue, please take the following steps:

1. verify that there is no existing entry for "/" in /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf
2. create a backup copy of the file /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf:

   # cp /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf.bckup

3. add the redirect entry:

   # echo "/ namedpipe /var/run/vmware/vpxd-webserver-pipe redirect allow" >> /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf

4. check the file to verify that there are no duplicate entries. For example, in VCSA 7.0 Update 3k, the file should look similar to this:

   # cat /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd.conf
   /    namedpipe    /var/run/vmware/vpxd-webserver-pipe    redirect    allow
   /Query    found    8080    allow    reject
   /pcnotification    local    9232    reject    allow
   /vsan/sdkTunnel    namedpipetunnel    /var/run/vmware-vsan/vsan-sdkTunnel-pipe    allow    reject
   /vsanHealth    namedpipe    /var/run/vmware-vsan/vsan-sdk-pipe    redirect    allow
   /vws    found    8080    allow    allow

5. restart all vCenter services:

   # service-control --stop --all && service-control --start --all
