I am facing issue when I am trying to validate the security certificate while calling the APIs using system function

![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/0/002d8cca2b5a122b1904354388a0ac94e989a5f1.png)

as shown in above image, currently I am using the **bypass\_cert\_validation** as **True** and it is working fine with this. But when I set value to **False** then it gives me **500** or sometime **200** error.

Looking for possible solution/workaround for this kind of issue.

This probably means the CA used to sign the certificates these servers are using are not trusted. This is common when they are internal servers signed by an internal CA.

You can add the CA certificates to Ignition's trusted CA list by adding to the supplemental certificates folder.
