Preventing repeated PR_END_OF_FILE_ERROR messages

I have started getting repeated PR_END_OF_FILE_ERROR (and earlier some ERR_CONNECTION_CLOSED) messages when I first go to websites. After some exploring the only solution I have found is to manually disable "encrypted web scan" under Online Threat Prevention settings (although this seems to rather negate the point of this setting). Once I do this, and turn on protection immediately) I can access a website and pages within it.

Similar behaviour occurs in Firefox and Edge so it is not a browser issue as far I can see. In Edge the message is more Windowsy (and less helpful) -

"Hmmm… can't reach this page It looks like www.******.xx closed the connection"

So, can anyone advise a way to stop this behaviour?

Thanks, Mark

  • Hello @MarkWin,

    This could be related to a DNS issue. Try to switch to Google DNS and see what happens next. You can follow the steps from this article:

  • Thanks for your suggestion but it has not resolved the problem.

  • Thanks for your detailed suggestions. I tried following the somewhat complex series of steps but I appeared to hit a problem with the online support system in that the file I thought I needed to upload was too large.

    Before trying again I decided to do some more searching and found references to fake-ca.crt - found in /Program Files/Bitdefender/Bitdefender Security/mitm_cache. There were no Bitdefender certificates listed in my browser.

    I installed this and the issue appears to have been resolved.
