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:
I hope that you find this information helpful.
