Hi @kjosern 👋

Welcome to the Kinsta Community!

You might encounter the error “_ **cURL error 60: SSL certificate problem: unable to get local issuer certificate** _” because the Devkinsta app uses a self-signed SSL certificate only. If you use **curl -k** to bypass SSL, it should provide the correct **curl** output. I am not sure, though, if this is doable within the optimize plugin. But you can check out the screenshot below as an example:

You can also refer to this lengthy discussion thread for possible workarounds to bypass this self-signed SSL limitation:

> Kevin, I’m on Big Sur 11.6 and did not change versions before the issue started. I’ve also found a workaround for Firefox If you go to Firefox \> Preferences \> Privacy & Security you can add the server as an exception Clicking View Certificates as seen in screenshot will allow you add the full domain name (including port value if different) as an exception which so far allows me to bypass the warning in browser.

I hope that you find this information helpful. 🙂
