When I tried to download patches via a freshly installed VMware vSphere Update Manager today I received the following error:
https://hostupdate.vmware.com/software/VUM/PRODUCTION/index.xml;
hosting the patch definitions and patches cannot be reached or has no patch data
Although we configured a proxy including the appropriate account it would not work. As suggested in this KB article I removed the “http://” part of the proxy address but still it bailed out with the error above. After trying several combinations I noticed that the proxy was actually a PAC address instead of a proxy server. A PAC basically serves a list which contains the proxy details of the environment. This comes in handy when you’ve got multiple proxy for redundancy… In this case VMware Update Manager wasn’t fond of the PAC file. When I used the address of the proxy server instead of the host server the PAC file it worked like a charm…
