Enfold: theme update: error reports

I am often confronted with error reports on the Enfold “Theme update” page on customer websites, when I try to release a theme update. In one customer website there is a permanent 403 error report for weeks now, supposedly caused by the Enfold username and mail address (…”could not be accessed”). But I can’t find any problem. I am even logged in at the themeforest account of the customer – and there is no error report.

Fortunately on the Enfold theme update page there is a link “Check manually” – and the theme update worked out – so I have now the latest theme version. But the error report remains – please read the following report. Already the headline “Pleas verify the key” is irritating and seems to be not logical, because I verified the key before, of course. Otherwise the error reports are completely different. So here is the complete report:

Please verify the key.
We checked the token on 2020/08/20 08:27 and we were able to connect to Envato and could access the following information:

Your purchases
Username could not be accessed (needed for your information only)
E-Mail could not be accessed (needed for your information only)
Following errors occurred:

username Errorcode 403 returned by Envato: Forbidden:
– code: not_authenticated
email Errorcode 403 returned by Envato: Forbidden:

If you ever edit the restrictions of your personal token please re-validate it again to test if it works properly
