Hello,
"Unable to verify the first certificate" message for a request on one domain.
If i uncheck “Enable SSL certificate verification”, i have no longer the message.
I check with success, the SSL certificate with web browser.
But i want to understand the problem.
On an other server, config identical, i don’t have this message.
Certificates got with Let’s encrypt.
The only difference is the CA issuer (R3 or R10).
How can i debug please ?
Thanks in advance.
