Asp net err ssl protocol error - Исправление ошибок и поиск оптимальных решений проблем

First, check your site web binding detail by the following detail:

Open visual studio, select your project.
right-click on the project and select properties.
under the Web tab and check your project url.

make sure there no such setting in your web.conifg file like below:

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Strict-Transport-Security" 

        value="max-age=16070400; includeSubDomains" />
      </customHeaders>
    </httpProtocol>
</system.webServer>

When the browser sees this, it will remember, for the given number of seconds, that the current domain should only be contacted over HTTPS. In the future, if the user types http:// or omits the scheme, HTTPS is the default.

Clear your browser cache.

Another thing you could try to find the cause is open chrome and type chrome://net-internals/#hsts in the address bar and search for localhost:

The query shows “localhost” as being in the list of domains in the HSTS set.

The solution is deleting the domain from the cache. type “localhost” into the Delete domain text field, and hit Delete. After doing that when you query for “localhost” again you will receive a “Not found”.

Hi Muhammad Naveed Haroon,

You can try to browse the site using other browser(s) and check if same error appears.

Besides,
this blog explained how to fix ‘ERR_SSL_PROTOCOL_ERROR’ on Google Chrome, you can try the possible solution, such as clearing Browsing Data, enabling all SSL/TLS versions etc.

With Regards,

Fei Han
User1281381861 posted

Are you running local host site with https protocol?

Have you set correct SSL certificate on your website?

Please check the expiry date of your SSL certificate.

From what we’ve seen in the «regular» failed HTTP requests a status code of zero usually means two things:

The server is down
Authorization didn’t happen.

In this case we saw the negotiation request sent, with an immediate failure. Our server was up and running and we had set up CORs. We were stumped.

Indeed the seemingly ubiquitous nefarious ugly and mystery error showed:

🍋🍋🍋🍋🍋

Failed to load resource: net:: ERR:SSL_PROTOCOL_ERROR

We see the Websocket failure in this trace:

Its content showed this:

Not much information here. Let’s look at backend. The output window showed this interesting clue.

2020-06-10T09:50:48.3243364-05:00 | [Warning]
Message: Authorization failed for  at RouteEndpoint

Enter fullscreen mode

Exit fullscreen mode

This Error is instantly painful when it happens because the journey to solve it is difficult.

This error does not deal with non secure requests. If you are running an http site, not https, websockets is still able to connect, so we know that SignalR works on both schemas. However, if you are running just http then be aware that you need to add redirect middleware.

We never figured the root cause of this error, but we did find a solution. We made sure our site was using HTTPs, this fixed the problem.
