Solution for PR CONNECT RESET ERROR
Solution # 1 Checking network cables and restarting the Wi-Fi router
Let’s start with you with something really trivial. Make sure all network cables are properly connected to your PC and Wi-Fi router. In addition, we recommend rebooting the router itself a couple of times: it could start working with errors and literally prevent you from connecting to some or all of the web resources.
Solution # 2 Disable the proxy server
Some users claim that they managed to get rid of the PR CONNECT RESET ERROR by turning off the proxy server in the LAN settings. To disable the proxy server, you need to do the following:
- press Windows + R to bring up the Run window in front of you;
- write the value controlto an empty line and press Enter;
- in the view mode, select large or small icons (believe me, it will be easier this way);
- open the section “Browser properties”;
- go to the “Connections” tab and click on the “Network Settings” button;
- uncheck the option “Use a proxy server for local connections (not applicable for dial-up or VPN connections)”;
- save changes and close all previously open windows;
- restart your computer.
Open your Mozilla Firefox and check for PR CONNECT RESET ERROR.
Solution # 3 Clearing the DNS cache and resetting the TCP / IP protocol settings
If you are experiencing any network problems, then you should definitely try resetting the DNS cache and TCP / IP network settings on your computer. This is done with a couple of elementary commands. Do the following:

- netsh int ip reset
- netsh int ip reset resettcpip.txt
- netsh int ipv4 reset
- netsh int ipv6 reset
- ipconfig / flushdns
- when finished with the commands, restart your computer.
This method can solve a whole bunch of various network problems. Open your “mozilla” and try to go to the required web resource. The PR CONNECT RESET ERROR might have disappeared by now.
