Causes of Google Chrome’s ERR_SSL_PROTOCOL_ERROR
Let me first give you a few explanations for this error. There could be further mistakes as well. However, I’ve outlined the most frequent causes of the ERR_SSL_PROTOCOL_ERROR. These are the most frequent causes of this error:
- Browser extensions are blocked by the Firewall.
- Inaccurate time and date
- The cache on a browser
- The system’s SSL state.
How to Fix Google Chrome’s ERR_SSL_PROTOCOL_ERROR
If the problem persists even after refreshing the website or deleting the cache, it disturbs us. This mistake in Google Chrome needs to be fixed because it cannot be ignored.
We have provided you with the most effective and appropriate methods for removing the ERR_SSL_PROTOCOL_ERROR from Google Chrome.
Method #1 Sync the System Date
There are times when issues arise because of a few minor systemic faults. Therefore, the erroneous date in your system is one of the most frequent causes of this ERR_SSL_PROTOCOL_ERROR.
The time on the system and the time on the server hosting the website should always be in sync. Therefore, you may quickly change the date and time on your system manually or have it automatically sync with the internet. To do this:
Step 1: Select “Settings.” Toggle to “Date and time.”
Step 2: There will be an option to “Automatically adjust for Daylight Saving Time.” Activate this selection.
Step 3: Verify that the mistake has been resolved.
Your Chrome browser’s ERR_SSL_PROTOCOL_ERROR will be resolved by doing this.
Method #2 Delete the Browser’s Cache
Users with a background in IT or with a basic understanding of IT concepts and web development might understand the browser cache with ease.
Web developers were aware that CSS changes would not take effect if the cache was not clear. Cache removal is a pretty easy technique. Getting rid of the cache
Step 1: On your keyboard, simultaneously press the “Control,” “Shift,” and “Delete” buttons.
Step 2: The system will direct you to the “page of the browser’s “options.”
Step 3: Select “AA Time” as the range in the “Time Range Section.”
Step 4: Check every box except from “Browsing History” (you can delete browsing history too but be aware you will lose all the history of your searches).
Step 5: Click the “the “Enter” key.
Your cache will be cleared once you have completed all of these procedures. Lastly, make that the issue has been resolved.
Method #3 Remove Host Files or Restore Default
To restore the host files, there are essentially two options.
Downloading the “host file storage utility” is the first available option. The mistake in the web browser will be automatically fixed by this utility.
Manually generating the host file is the second approach.
The location of the host file is “C:WindowsSystem32driversetc.”
The host file must be removed first. Next, update the file with the proper code. Sometimes host files get faulty, which results in inaccurate information being prompted. You may quickly delete and update the file to totally remove the ERR_SSL_PROTOCOL_ERROR.
Method #4 Clear the SSL State of System
Procedures for resetting the “SSL State of System”
Step 1: Open the Google Chrome web browser. There will be three dots in the top-right corner of the webpage. Toggle those three dots.
Step 2: A menu for navigation will be displayed. Go to the screen’s top-left corner and click the “Settings” button.
Step 3: Next, choose the “System” option under the advanced drop-down menu.
Step 4: Choose “Open Proxy Settings,” which will bring up a window for “Internet Properties.”
Step 5: Navigate to the “Content” tab.
Step 6: Select “Clear SSL State” after selecting the Content tab.
Step 7: Refresh or reload the website.
After you reload the page, the error will go away. A very easy fix for the ERR_SSL_PROTOCOL_ERROR is provided here.
Technique #5 Modify the antivirus settings
You can change your antiviral settings by carrying out the subsequent actions:
Step 1: Navigate to your antivirus software‘s “Antivirus Settings.”
Step 2: Find the “SSL Protocol” under the “Advanced Settings” section of your antivirus’s settings.
Step 3: Verify that the “SSL Protocol” is being scanned by the antivirus programme.
Step 4: If the functionality is scanning, turn it off and replace it with “Ask about unvisited sites.”
Reset the settings to default if the error still occurs.
We are unable to show you the exact navigation options of every antivirus programme because there will be variations among them.
Method #6 Disable the QUIC Protocol using:
The secure server connection is established through QUIC. Quick UDP Internet Connections is the acronym.
TLS and SSL are similar protocols. Chrome already has it turned on by default. Rarely will this QUIC Protocol conflict with the websites’ SSL Protocol, resulting in the ERR_SSL_PROTOCOL_ERROR.
How to stop using the QUIC Protocol:
Step 1: Type “chrome:/flags/#enable-quic” in the address bar of Chrome and press “enter.”
Step 2: Select “QUIC Protocol” from the menu at the top of the display. Uncheck the “QUIC Protocol” checkbox.
Step 3: Refresh the website.
This will fix the ERR_SSL_PROTOCOL_ERROR.
Method #7 Modifying the Internet Security and Privacy Settings.
Everyone is concerned about security and privacy, especially when using the internet. As a result, most users maintain a high level of security and privacy “High“. This could occasionally prevent the SSL connection. To modify the settings, adhere to following steps:
Step 1: Type “Control Panel” into the search box to launch it.
Step 2: Go to “Internet Options“.
Step 3: Currently, go to the “Tab “Security“. Keep “Medium” as the security level.
Step 4: Select “Medium” for the privacy setting under the “Privacy” tab.
Step 5: Refresh or reload the website.
The browser will no longer display the ERR_SSL_PROTOCOL_ERROR.
Method #8 Activate all TLS/SSL versions using:
Make sure to try this approach if the previous one failed to resolve the issue. In order to use this strategy, all TSL/SSL versions that are reloading all the antiquated and unsafe SSL Protocols must be activated.
If the solutions listed above don’t work to fix ERR_SSL_PROTOCOL_ERROR, attempt this process of activating insecure SSL protocols. The following actions should be followed to activate all SSL/TSL protocols:
Step 1: Select “System” under “Advanced Settings” in the Chrome browser.
Step 2: Select “Proxy Settings.”
Step 3: Click on the “Advanced” tab now.
Step 4: Go to “Security” and select “TSL/SSL Protocols,” checking all the boxes.
Step 5: Restart your browser.
Verify the ERR_SSL_PROTOCOL_ERROR has been resolved.
If the aforementioned techniques didn’t successfully correct the mistake, try this one.
I sincerely hope that these solutions were successful for you and that your Google Chrome browser is now free of the ERR_SSL_PROTOCOL_ERROR. Always begin with the first approach; if it doesn’t correct the issue, move on to the next method, and so forth. Any of the aforementioned techniques, when used correctly, will eradicate the mistake.
Try activating every SSL/TSL version if all other approaches prove ineffective (hoping it won’t be the case). However, it is advised against using this method as it can compromise the privacy and security of your browsing. Continue browsing contentedly right now. 7
