I've checked our records and found no similar issue like yours. When did you encounter this error? Additional details would help. For now, we can check to see if this is a cache-related issue.
Sometimes, the data overload in your browser causes lag or errors. Now let's start off by accessing a private browser. You can use the keyboard shortcuts below:
Internet Explorer & Mozilla Firefox: Ctrl + Shift + P
Google Chrome: Ctrl + Shift + N
Safari: Command + Option + P
Then, if you can continue on what you are supposed to do, you can go back to your regular browser and clear its cache to reset the data allowance in the browser. But if you are still not able to get through, you can use another browser instead.
I'll wait for your response to the details of this error. Take care.
