This Monday I have noticed that I can not login my developer org with custom domain.
The problem in brief: certificate for *.salesforce.com does not allow to add exception for subdomains. So I totally blocked - can not log into my salesforce from FF, Safari, Chrome
Did I miss some notification about certificate updates? How can I restore access to my org when I even can not login?
Error description in chrome:
xxxxxxx.my.salesforce.com normally uses encryption to protect your information. When Google Chrome tried to connect to xxxxxxx.my.salesforce.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be xxxxxxx.my.salesforce.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.
