After everything working just fine last night, im suddenly getting this error on fetch requests but only on local dev site. The live site works as it should no problems there.

node_modules\next\dist\server\response-cache\index.js:99:36 {
  cause: Error: unable to verify the first certificate
      at TLSSocket.onConnectSecure (node:_tls_wrap:1550:34)
      at TLSSocket.emit (node:events:514:28)
      at TLSSocket._finishInit (node:_tls_wrap:967:8)
      at ssl.onhandshakedone (node:_tls_wrap:743:12) {
    code: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE'
  }

Again everything was working as it should last night. Just went back to the already opened project window and got this issue. I have restarted local dev server, cleared cache and cookies, and even rebooted the pc. Still problem....
