Guide: Fix ‘Err_quic_protocol_error’ Issue in Chrome Browser
The Err_quic_protocol_error is an intermittent error that can be tricky to fix. However, Compsmag has the answer for how to fix it. Here is how:
- Make sure that you are using the latest version of Chrome.
- Try different browsers and see which one has the Err_quic_protocol_error.
- If you still cannot browse sites with Chrome, then you may need to update your browser or install a new extension.
Google Chrome is a very stable browser that has been around for years. It is used by millions and is the foundation for other browsers using Chromium.
The release version of the browser is very stable. One thing to consider is that the guys at Google like to experiment. They recently had to roll back a change to auto-play audio because it accidentally muted online browser games. While rare, these things do happen and are the price we pay for an advanced browser.
Fixing the Err_quic_protocol_error
There are a few websites that offer to fix this error with a download. It doesn’t need one and is a very simple solution. Although I don’t name names, these websites offer a patch specific to this bug, so use them with caution.
The QUIC protocol is an interesting technology, but I’ll show you how to fix the error before discussing it.
The Err_quic_protocol_error seems to happen on fiber optic networks with fast routers. I have no idea why it is happening, but slower ADSL or ADSL2 routers don’t seem to have this problem. Anyway, here is how to Fix it.
If you’re experiencing Err_quic_protocol_error, there are a few things you can do to fix the problem. First, check the QUIC flag as described above to prevent it from happening again. If that doesn’t work, you can uninstall Chrome and then reinstall it. After you reinstall Chrome, make sure to check the QUIC flag again to prevent this issue from occurring in the future. ..
If you have to reinstall Chrome, this method will keep all your favorite settings and favorites. It will replace the Chrome core files with new ones and will choose up bookmarks and everything else from elsewhere on your computer. Now Chrome should work fine without the Err_quic_protocol_error.
The QUIC protocol
Google is working on a new network transport mechanism called QUIC. This protocol is intended to be much faster than TCP, and it is hoped that it will eventually replace the current standard. By reducing the overhead of TCP and the streams instead of doing them in sequence, QUIC is destined to be much more efficient.
A TCP connection involves a single stream of data and a lot of back and forth between your browser and the destination. If one TCP packet crashes, the others behind it keep crashing, causing a delay.
QUIC is designed for speed. Instead of the multiple installation messages of TCP, QUIC does it in one message. QUIC also uses UDP multiplexing which allows more messages to pass through even if one is stuck. It also includes built-in congestion control for maximum efficiency. ..
The new feature from QUIC is error checking. It easily handles lost packets and manages the loss with speculative retransmission. TCP uses congestion avoidance, but this is limited to faster or less congested networks. Slower or unreliable networks cause TCP headaches.
Google has been driving the development of QUIC for six years now, but it is still in development. If you want to learn more about QUIC, this resource is excellent.
