CURL Error: SSL certificate problem: unable to get local issuer certificate - Code 60

After update to 7.82 we are no longer able to access the whmcs admin due to this error

CURL Error: SSL certificate problem: unable to get local issuer certificate - Code 60

I have opened a ticket, and this is the reply i got

"The error CURL Error: SSL certificate problem: unable to get local issuer certificate - Code 60 means that your server is unable to validate remote SSL certs. Typically this means that your servers ca-bundle is out of date and updating it will resolve the issue."

But it was working fine before the update, so surely if it is a server problem, it would have never been able to validate ssl certs prior to the update and other sites on the server would also be having this issue.

Hi @snake,

This is a licensing error, indicating a connectivity issue between your server and our licensing infrastructure.  There have been no changes in this area between 7.7 and 7.8 so the timing is likely coincidental.

We've not received similar reports from other users, so please do investigate this matter with SSL cert validation on your server with your server admin to resolve it.

how this mysteriously stopped working between 7.7 and 7.8 I guess we will never know then.

But I managed to solve it by downloading a new copy of the cacert from the curl website and copying it to server and pointing curl to this file.
