If you click the link in the error and look at the error number (77) you’ll see this:
CURLE_SSL_CACERT_BADFILE (77)
Problem with reading the SSL CA cert (path? access rights?)
This means something like corrupt file, bad file permissions, file is missing, etc. I’d recommend downloading the latest cURL certificate, replace your existing one, make sure you have appropriate permissions, restart IIS, and retest. There are guides online that explain how to do this; this is not an osTicket issue.
Cheers.
