No Data Received

When typing in a password for a password protected page, I am receiving the error:

No data received
Unable to load the webpage because the server sent no data.
Reload this webpage
Press the reload button to resubmit the data needed to load the page.
Error code: ERR_EMPTY_RESPONSE

My cache has been cleared and I’ve refreshed the page – no luck.

I have not yet checked in with the server company. Wanted to try this forum first.

Let me know if anyone has any advice/questions. Thank you!
