My wife's comp couldn't access google.com (gmail) today until I unticked IPv6 in adapter settings. Didn't seem to have any problems with other sites and my comp is fine. 

 

No idea why IPv6 is problematic on this one machine. Guess I just leave IPv6 disabled.

 

The adapter is an onboard one in a Dell Optiplex 780.

The error reported is:- ERR_QUIC_PROTOCOL_ERROR

 

Same problem with Chrome and Edge. The problem page seems to be https://accounts.google.com/

Yeah, I'm seeing slow response (intermittently) from Google since the IPV6 went live.  Haven't really investigated too much; but the issue does seem to be device-agnostic (i.e. all my devices occasionally have slowdowns on Google traffic).

 

@Sounddude - any known issue in this area?

Go here for a fix for Chrome https://appuals.com/fix-google-chrome-error-err_quic_protocol_error/

 

It involves disabling the 'experimental' QUIC protocol.




I fix stuff!

Not something we have come across before?

 

Can you guys confirm what modem you have and the firmware version?

MadEngineer: What happens if you run a nslookup IPv6.google.com from command prompt?

 

Technically, this is from a BASH shell, rather than a command-prompt; but I don't think that's going to make a huge difference:

james:[~]$ nslookup
> ipv6.google.com
Server:        121.98.0.1
Address:    121.98.0.1#53

Non-authoritative answer:
ipv6.google.com    canonical name = ipv6.l.google.com.

More interestingly, "ipv6.l.google.com" doesn't resolve:

> ipv6.l.google.com.
Server:        121.98.0.1
Address:    121.98.0.1#53

Non-authoritative answer:
*** Can't find ipv6.l.google.com.: No answer

I've got the following set in my router under Advanced Setup/DNS: "Select DNS server from available WAN interface"; and I'm pushing my router's IP address for DNS via DHCP.   Also "DNS Proxy" is turned off.

^ based on "Server: 121.98.0.1" your dhcp server is pushing orcon's dns server, not itself (assuming that machine is on dhcp not static)

 

also, for nslookup under bash you'll need to add -query=AAAA or set query=AAAA

I can assure you it is configured to push itself; I just checked.  However, as I also previously stated, "DNS Proxy" is disabled; which presumably is overriding the DHCP DNS-setting in the router.  That's my assumption - I don't have source code for the firmware, so I can't check!  :-)

 

MadEngineer: also, for nslookup under bash you'll need to add -query=AAAA or set query=AAAA

 

Wow; long day at work today obviously - I should have thought of that myself.

 

james:[~]$ nslookup
> set type=aaaa
> ipv6.l.google.com
Server:        121.98.0.1
Address:    121.98.0.1#53

Non-authoritative answer:
ipv6.l.google.com    has AAAA address 2404:6800:4006:808::200e

 

Better.  Also, this:

 

james:[~]$ ping6 ipv6.google.com
PING6(56=40+8+8 bytes) 2404:4404:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX --> 2404:6800:4006:808::200e
16 bytes from 2404:6800:4006:808::200e, icmp_seq=0 hlim=52 time=36.471 ms
16 bytes from 2404:6800:4006:808::200e, icmp_seq=1 hlim=52 time=46.495 ms
16 bytes from 2404:6800:4006:808::200e, icmp_seq=2 hlim=52 time=40.209 ms

...and I've turned off the IPv6 on my router.

Just seemed to be causing too much instability and timeouts. My phone in particular really didn't like it; I was getting WiFi dropouts, really bad performance on basic things [browsing and email, for example], etc. It's a fairly modern phone running Nougat [Android 7.0] too, which is odd.

Pity.
