Unable to do development gulp serve, ERR_CONNECTION_RESET. with latest version of KIS 21.1.15.500 [Fixed in 2021MR2]

[Guest]

Another workaround is:

- Open Settings - Additional - Threats and exclusions - Specify trusted applications - Add
- In the opened window click on the search icon (magnifier) and type web browser name (Chrome for example)
- Choose browser executable from the list, double click on it and choose Do not scan all traffic, Only for specific IP type "::1"
- Close settings, restart pc and check.

 

The issue should be fixed in MR2 version.

Another workaround is:

 

Using 127.0.0.1 instead of localhost. It will be OK during the redirection from port 5432 to 4321.

Thank you everyone for your replies.

I have kaspersky certificates installed when i check with certmgr.msc.
I unchecked “Scan secure traffic in Mozilla applications” but the issue still exists. Also this is not browser dependent as it is same behavior in chrome and edge too.

Basically when I add the webpart to page, this should be the expected outcome. I will try other suggestions and will post the outcome. I have restored all the original settings on KIS now.

Hi all,

I have reverted back all KIS settings. I added chrome to trusted applications, then I choose " Do not scan all traffic, Only for specific IP type" and gave "::1" and restarted the PC.
Now the site loads. But when I added the webpart on the page ,it loads sometimes and sometimes it just displays nothing. In the console, I can see a lot of errors.

Hello @San2020, 

You’re most welcome☺ !

The MR2 fix @Anton Mefodys is referring to is due late October/November 2020. 

If Kaspersky Technical Support come up with any other solutions, in the interim, please share the information with the Community. 

Thank you🙏

@Flood and Flood's wife ,

I will wait for the MR2 fix. In the meantime, as the website seems to load correctly with the settings that you told, I wanted to understand what exactly happens when I set  " Do not scan all traffic, Only for specific IP type" and give "::1" . What is meant by “::1”? I would also accept your answer as the temporary solution until the fix is released. But what exactly is meant by “::1”?

Hello,

Have you try to my solution? Change the serve.json file content in your project config folder.

And make sure “gulp trust-dev-cert” command is running before you do add item in your project. As my side, There is no problem at all.

Hi Zhang,

Thank you very much for the response. Yes your solution will also work.
Thanks a lot for taking your time and installing all the software and moreover also creating a video for the same.
However I don't understand what is meant by  “::1” setting which I did as per Anton's workaround.

Hello,

All you need to know is that this is a magic symbol to respond to requests from your local computer, such as 127.0.0.1 or localhost, this is the loopback address of IPv6.

Hello，

As my test, This issue has been fixed in the future 2021 MR2. Let’s wait for this build release.

Regards.

I have received response from support that this will be fixed in MR2 in  late October - early November.
I was asked to install KIS2020 till then or try the following...

1. Open Application Control settings - Manage applications - search for the browser, e.g. Chrome -> find chrome.exe in the list - open its details and rules - navigate to Exclusions tab. Tick an option to 'Do not scan all traffic' - for specified IPs - add 127.0.0.1 here.

2. Restart the computer, then try to access https://127.0.0.1 in Chrome (or other browsers).

If it does not help:
3. Add the following string to the hosts 127.0.0.1>file:
127.0.0.1 test-site.com

The name may be different, test-site.com is just, for example.

Check the issue by using addresses:
https://test-site.com
https://127.0.0.1
