Mac Safari certificate error

Safari disable failed to open page after I change server certificate.

NSURLErrorDomain error -1202.)

I can't find the problem certificate on KeyChain.


Any advise for reset certificate?


Thanks.

The usual textual accoutrements for -1202 are “The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xyz.example.com” which could put your confidential information at risk."


Open a browser connection into the server using HTTPS, and accept the offered certificate as trusted?


Or otherwise transfer over the public cert.


Or start your own certificate authority?


Or use a purchased cert?


The outdated certs on the client aren’t related to this.


Make CERTAIN your server DNS is correct. Launch Terminal.app on the server, and issue the harmless diagnostic command:


sudo changeip -checkhostname


That command should either indicate no changes are required, or should point to any issues identified.
