Yes, delete it. I have been through a number of forums researching the problem. It comes down to either your client is out of time sync with the server or there is an invalid cert.

I resorted to deleting that specific cert. That appears to have corrected my error.

4x4Wire does not use "secure sockets layer" which is noted by the :443 port identifier in the error message.

If a cert is required, you will be prompted to accept the new cert.

I have no idea how it appeared.
