How to deal with ERR_EMPTY_RESPONSE in browsers?

Question

Google Chrome

Hello dear. There was a problem out of the blue. Browsers worked well, everything opened. But at some point, chrome, when trying to open any site, began to give an error ERR_EMPTY_RESPONSE. In Google, he searches everything well, but when you click on the link, the site does not load. In mozilla, the same story, but an error, they say the server did not return the data. Opera opens everything, with a few exceptions. And yet, sites on the local hosting of the computer also do not open. Tried disabling firewall, avast didn't help. Reinstalling didn't help. Removing extensions didn't help. I recently installed java for myself, but I don’t know if this can affect the work of browsers, since 2 weeks after installing java everything worked fine.

Answer 1

This means that the server response has an empty body, for accuracy, take a sniffer and see what's going on.
