Lifecycle Manager - cannot upload ISO

[AllanGillies]

We have a problem uploading ISOs to Lifecycle Manager in vSphere Client version 7.0.3.00100.

The ISO in question is VMware-VMvisor-Installer-7.0U2a-17867351.x86_64.iso. The upload process starts, but always fails at exactly 256.02.MB with the message "An unexpected error has occurred".

We found a discussion thread which describes a similar problem here: https://communities.vmware.com/t5/Update-Manager-Discussions/ISO-Import-Vcenter-7-Lifecycle-manager/td-p/2823004. As the article suggests, have tried downloading a fresh copy of the ISO and reset the Update Manager database - but these have not helped.

All further ideas gratefully received!

Check the connection from the vCenter

1.) run curl -vvv https://hostupdate.vmware.com
2.) The output should look like:

# openssl s_client --connect hostupdate.vmware.com:443
CONNECTED(00000003)
depth=2 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root CA
verify return:1

verify return:1
depth=0 C = US, ST = California, L = Palo Alto, O = Broadcom Inc., CN = hostupdate.vmware.com
