I recently started getting the above error when trying to log into my 2 different on-line banking sites. Now I get the same error trying to go to homedepot.com site (not trying to log it to anything, just to bring up the site.
I did try shutting off Avast and then was able to visit the site, so it seems to have something to do with Avast. Another clue may be that with Avast on, I can visit the site on using a Firefox browser.
The ‘advanced’ buttom on error page gives this text [i]"www.homedepot.com normally uses encryption to protect your information. When Chrome tried to connect to www.homedepot.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be www.homedepot.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.
You cannot visit www.homedepot.com right now because the website sent scrambled credentials that Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later."[/i]
This had never been a problem until a few days ago. Any ideas?
I tried a connection using Firefox to see it is was a local issue.
There appears to be some issued with homedepot.com in that it is trying to load http page when the browser is trying to access secure https pages. See attached screenshot one of the error screen.
Also see - https://en.internet.nl/site/homedepot.com/1769119/ - this reports issues: “using a modern internet address (IPv6)” see screenshot two.
I don’t know if this might be the route of the problem or not.
After disabling the https scanning and you were able to connect to the site, was the connected url http (not https as in my first screenshot) ?
Whilst it is not advisable to disable https scanning, if the site is actually connecting to an http page/source I believe connection is still scanned by the Web Shield, but the connection isn’t as secure. This could increase risk of the connection being compromised as the data transmitted isn’t as secure.
“When enabled, the HTTPS scan protects your system against the malware delivered over HTTPS connections. When disabled, File Shield still scans all downloaded content before running any files.”
Thanks R@vast. The site still shows up as https://homedepot.com. I’m generating a support file now. Does it usually take a long time (it’s been going for 10 minutes now)…
I have the same problem. Some web pages are complaining for HTTPS certificate , because of the issuer. The issuer is “Avast root ca”.
It is only on Chrome browser, Edge can open that pages.
Removing and reinstalling the Chrome extension hasn’t solved it.
I have disabled the Quic/HTTP3 module and the problem is solved.
thanks for this feedback, it’s already a little better than disabling the “https scanning”
in “about:config” (firefox), you can also try to change “network.http.http3.enabled” to “false”
maybe some sites are now using this new protocol and some browsers and antivirus are not yet fully developed for ???
I had the same problem which started a week or so ago with PAYPAL - see attachment. CHROME refused to connect siting “scrambled credentials” - which seem to come from Avast. If I disable HTTPS Scan, Chrome opens Paypal no problem. Note that MS Edge works with or without HTTPs Scan enabled. Is this an @Avast update problem whcih needs fixing? It’s damned annoying.
Please would someone update when this issue is resolved? I can see others struggling with major retailers etc (e.g. Home Depot) so it needs fixing!

This is nuts. I’ve had to disable Web Shield to visit regular websites, no idea why this is suddenly happening. Disabling “QUIC/HTTP3 scanning” did not solve the issue but also disabled HTTPS Scanning did.
