Issue in Variation in SharePoint Online

Hi,

I configured variations in my publishing site.  Following steps I took:

1. Created labels in English as source and german as target with all default settings.

2. Created hierarchies.

3. Modify the default.aspx in source site with some random content. 

4. From Pages library of source site, select the default.aspx and from ribbon click on 'Update all targets'. (I think even I skip, it will automatically propagate the changes to all targets.

5. In destination, once this modified default.aspx (with English content) is available. I clicked from ribbon 'Machine translation'.

6. After an hour or so I got an error in Variation logs as

'Machine translation of package /sites/abc/TranslationPackages/testuser@xyz.com/de-de-seiten-20171118T10172-0/de-de-seiten-0001.xlf  failed with error message : The file could not be translated due to an intermittent error in the system. Please resubmit this file for translation. If the file fails again with this error message, contact your system administrator.'

I have tried multiple times, but no luck. Any idea.

Thanks in advance
