Trying to set up OAuth2 with office 365. Once I save my settings I get the following error:
"URL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://login.microsoftonline.com/common/oauth2/v2.0/token"
Seems like your local cURL cannot get the local issuer certificate for the login.microsoftonline.com domain. This can be due to many reasons so you'll need to do some googling.
Supplying a new cacert.pem file and pointing php.ini to use it, resolved this error.
Nice! Yea this is a weird issue; you'd think your install of cURL has the appropriate certificates but guess not 🤷♂️
Is possible to explain how do you fix this issue?
I'm using windows iis with osticket.
Visit the URL in the error and it should tell you possible resolutions. If all else fails do some googling!
