I’m having trouble logging in to my account since the migration to AWS

Following the recent migration of Clickatell’s infrastructure to Amazon Web Services, some of our customers may experience issues when trying to log in to their accounts. If you’re having trouble logging in to your account, you may need to flush the DNS cache on your computer.

Operating systems are designed to cache DNS records, which allows for faster website lookup and loading. When a website is moved from one hosting service to another, it may be necessary to flush your DNS cache in order to retrieve the new records. Failing to do this will mean that your computer will continue to store the old incorrect address of the website, thereby preventing it from being loaded properly.

Each operating system has its own DNS caching service. To flush your DNS cache, simply follow the instructions below according to your specific operating system. If you still experience any issues, please contact our support team who will be able to assist you further.

Flushing your DNS cache in Windows:

Go to Start / Windows icon -> Enter cmd and a command prompt window will appear on your screen.

In the command prompt window type the following and press enter:

Ipconfig /flushdns

Flushing your DNS cache in Mac OS X:

The commands for flushing your DNS on Mac OS X differ slightly depending on the OS X version that you’re running. Open the terminal on your computer and run the command corresponding the version of OS X that you’re running.
