ERR_HTTP2_PROTOCOL_ERROR on particular sites

  • Author

Hi, I have Kaspersky. I’ve run into an issue when it comes to accessing "https://mapgenie.io/tarkov" [Link disabled] as well as a couple other sites, I simply can’t access them and get given an ERR_HTTP2_PROTOCOL_ERROR message.

this is an issue i’ve tested across chrome, edge & firefox.

I’ve tried flushing DNS, changing DNS servers, reinstalling KIS and a few other tricks but non of that works.

However when I set the domain to a trusted address in my network settings or simply disable Kaspersky internet secirity i seem to be able to access the sites again.

I’ve looked through other forum posts and found no other possible fixes so I wanted to ask here as I don’t particularly want to keep these sites as trusted or disable my antivirus to view them.

 

any help would be greatly appricated!

Hi Flood,

I am also having the same issue. Somehow the same websites are workingin Brave browser and issue is only with chrome.

Fyi.. it works for me after disabling the “Encrypted Connection Scanning” which I would prefer to keep enables.
 

 

Hi @technoholic.me , 
Keeping the option “Do not scan encrypted connections” enabled is not safe and not recommended. 

You can as a workaround add the problem sites to exclusions via Settings → Network settings → Trusted addresses → Add.

Hi @DR_NOMAD , @Goro , @Shane , @Dre , @onova , @imusingkasperskyyay , 

Do you have Safe Kids installed on the machine? 
What is its version? You can check by hovering the mouse pointer over the Safe Kids icon in taskbar or by right-clicking and selecting “About”. 


If you already sent a ticket to technical support, please PM me its number.

Just a heads up, I do not if it helps!

Yeah. I’ve noticed that a site I visited this morning is now giving me this error?

The web page at https://motopress.com/ might be temporarily down or it may have moved permanently to a new web address.

Disabling Kaspersky allows the site to work correctly?

Hi all,

 

Thanks for feedback. We'll let you know when we have any news about this problem.

@Jbennett360  Welcome.
 

It looks like this site is currently offline  🤔

Bizarre.

 

Disable Kaspersky and it works. Loads fine on mobile too with Wifi and data.

@Jbennett360

Correct , https://opentip.kaspersky.com is reporting “Good”.

 

Yep. Obviously an issue with Kaspersky at the moment then.

Hi all, we are investigating, sorry for the trouble. 
As a workaround (if you absolutely trust the site) add the problem site to exclusions via Settings → Network settings → Trusted addresses → Add. 

I am also having the same problem with a lot of different websites. This same problem happened a few weeks ago and was fixed now it seems to be back.

Any chance you could give more detail as to what’s happened and why once it’s resolved? If this is going to be a thing that pops up every now and again and causes these issues, then it might be that I need to look at alternative security suites.

 

Appreciate your communication on this though :)

Got the same error for https://backpackforlaravel.com/

Please investigate too. Thank you!
