Several Plot Hound users on iOS alerted us to an issue with logging in to Plot Hound on their iPhones and iPads. After entering their username and password, they were presented with an "index.html Login failed - error()" message. This issue did not affect Plot Hound users on Android.
This error was traced back to an issue with one of our SSL certificates. We have replaced the certificate and the issue has been resolved since June 16.
We understand that many people use Plot Hound as a core part of their business and we have put in place safeguards to ensure that service interruptions like this do not occur in the future.
