Fix ERR_SSL_PROTOCOL_ERROR by clearing your SSL Stat
If neither of the above works, clearing your SSL State is the next thing you should try. Follow the steps below to do so:
First, go to Customize and control Google Chrome, the three dots you see just below the X (close) button.
Now click on Settings.
Scroll down the page and open the Advanced Settings.
Go to Open proxy settings by scrolling down or searching in the search bar.
A window named ‘Internet Properties’ will open up.
Go to the Content window and click on the Clear SSL State Button.
Note: I did the same steps for https://mymiseqweb.com/ my site and it got fixed!!
