I have an old mac (2015) and started getting this recurring error from various sites & have tried Safari and Chrome:
502 BAD GATEWAY
Certificate verify failed: unable to get local issuer certificate
One possible cause is a VPN so I want to deactivate it to test this theory, I admit this is a last ditch attempt as I’m pretty convinced the Mac is just old and needs replaced.
Can I deactivate it without uninstalling it?
