Error only in production "This site can’t be reached" (RCA: Very large data in textbox)

I just get a "This site can't be reached" "The connection was reset" "ERR_CONNECTION_RESET".

There can be many other reasons but hopefully this will help if all other aides did not help.

Essentially, the problem to this specific problem was the firewall has a limit on the amount data that can be transported. My textboxes contain a lot of data (in the thousands of bytes). If I remove the data in the textbox everything works in production. My local system does not have this limitation so this works in my environment.
