ESX4 “Web Access” 503 Service Unavailable Error


KB ID 0000150 Dtd 27/11/09


If you connect to an ESX4 Server and attempt to "Log onto Web Access" you get a 503 Service Unavailable error.

This is because unlike EXS3 the web console is disabled, well not strictly true the service is usually running but the firewall (on the ESX server) is blocking it.

505 unavailable



1. Log into the ESX Host with the VI Client software. (Note: If you don't have the VI client you would normally be stuck in a Catch 22). However you can log onto the ESX Console as root and issue the following command;

service vmware-webAccess start

2. Select the ESX Host > Configuration > Security Profile > Properties > Locate vSphere Web Access > Tick it.

security ptofile

3. Then click Options Select Start and Stop with the host > Restart.

esx auto start

Note: Post ESX host reboot you may see 503 Service Unavailable Errors for a few minutes go and have a cup of coffee by the time you come back it will be up.
