Hello,
I didn't understand if I need to give you more details or if you're already considering my question?

This message appears when I go to the preferences of the Amin console, and I click on "retrieving the HTTP server certificate"

I forgot to mention:
tests performed with:
server: WAPT1.8.2 under CentOS 7.8;
consoles: Windows Server 2016

Hello,
in my company, we have a certificate*. I would like to use it in WAPT.
Integration with nginx doesn't present any particular problems. However, when I try to retrieve the certificate from the WAPT console,
the file format is incorrect (unable to create file... "C:\program...").
