Hello.
I manage a dedicated server on debian 9 with webmin 1.979, usermin 1.823 and virtualmin 6.16.
This server host multiple websites.
One of those is a webshop with Prestashop 1.7.
I've installed a plugin (sendinblue) that uses a webservice. Sendinblue needs to connect to my website by each time it tries, these's an error : 401 unauthorized.
Support of sendinblue told me to put this url :
https://app.sendinblue.com/integrations/api/
in a white list in webmin (or virtualmin)
but i don't know how to do that.
Can anyone help me ?
