I am trying to setup Lexicon on an older computer and I am receiving the attached message when trying to sign in, request password change, or create a new account. I have tried multiple internet sources and disabling firewall. It is Mac OS El Capitan 10.11.6.
Then Lexicon should be able to connect too. That error only shows if it can’t reach that page.
So there must be something blocking Lexicon, I don’t know what else it could be.
Try a restart, that can help too.
