Hello, I use engine-iso-uploader with ssh (and not NFS). It was working but now we have an error. I have tried two commands : engine-iso-uploader -v --iso-domain=lp-ducharmoy-iso upload eole-2.6.2.1-alternate-amd64.iso and engine-iso-uploader --iso-domain=lp-ducharmoy-iso list *and the error is :* ERROR: Fault reason is "Operation Failed". Fault detail is "Can't find storage server connection for id '7779c519-9f79-4339-81e0-f89f5e9f08b2'.". HTTP response code is 500. INFO: Use the -h option to see usage. I have read the /var/log/httpd/ssl_access_log , so we can read that API is not accessible : 192.168.83.83 - - [27/Sep/2019:12:01:06 -0400] "POST /ovirt-engine/sso/oauth/token HTTP/1.1" 200 310 192.168.83.83 - - [27/Sep/2019:12:01:07 -0400] "POST /ovirt-engine/sso/oauth/token-info HTTP/1.1" 200 323 192.168.83.83 - - [27/Sep/2019:12:01:07 -0400] "GET /ovirt-engine/api HTTP/1.1" 200 975 192.168.83.83 - - [27/Sep/2019:12:01:07 -0400] "GET /ovirt-engine/api/storagedomains HTTP/1.1" *500* 188 I have changed the admin password, do you think it could be come from this ?
