Some Websites load very slow

Help

So there is a possibility of a script that maybe could fix my Problem at least a little bit. Even it would check and update my IP in 6 hours, it would help me more as would never do that. Is it hard or complicated to make such a script?

22

I just wanna give a quick feedback of what I have done now. As we talk earlier in this thread, I updated the IPv6 Adress in the setupVars.conf File and run the command pihole -g. From this point and i don't know why, every site works perfect even when the IPv6 Adress changes and doesn't get updated by hand.
So maybe this could help someone to :slight_smile:

Thanks! I think I'll be pointing a few users to this thread to see if they have the same experiences and can solve the problem with the same results!

I had the same experience, found this thread searching for a solution, and the above IPv6 address change appears to have resolved my issue too. (Note that /etc/setupVars.conf is actually /etc/pihole/setupVars.conf.)

So, my steps were:

  1. SSH into the Pi Hole server
  2. Run ifconfig to get the IPv6 address (global, not local)
  3. sudo nano /etc/pihole/setupVars.conf
  4. Change IPV6_ADDRESS to the address from step 2
  5. Run pihole -g
  6. Log into routers settings
  7. Update the IPv6 DNS server to the new address
  8. Restart the Pi Hole server
  9. Restart the router
  10. Joy

In addition, I'm using Apple's latest AirPort/TimeCapsule, and my Pi 3 is wired to the back of it with Wi-Fi disabled, incase those details are helpful to anyone else.

Thank you for this, I had the same Problems for the last few Days and it seems my IPv6 Adress changed. I did it like JJJ suggested and everything works now again.

FYI: I could see that something was wrong because no IPv6 Adresses would show up in the Query Log.

We are currently investigating a separate approach, that is using ULA addresses instead of GUA addresses. At least with the ISP Deutsche Telekom, this seems to solve the issues we are seeing with frequently changing IPv6 GUA addresses.

I have two Global IPv6 addresses one with /64 and one with /128 at the end. which one did you use?

28

I'm not sure what your /128 address might be, but you should probably take the /64 subnet address.

Okay, thanks for the advice. Looks like I had other issues, my wife's MacBook and one of my Raspberry Pi's were fighting for the same IP address, to the point that the MacBook's host name was that of the Pi. Fixed that, then I started looking at my WiFi signal, the Mbps was extremely low on upload and download streams even though I'm in the same room with the cable modem. I live in an apartment and have to change WiFi channels periodically. I put my iMac back on an ethernet connection and everything improved, some sites like slashdot and linux.com still hesitate, but load much faster on a wired connection, of course. I'm going to keep tinkering around on my my wife's MacBook and my Linux laptop to see if I can improve anything on WifFi connected machines.

I just wanted to add to this - me too.

My ISP is BT in the UK which has a very large market share so this would also affect a lot of users in the UK.

Following along with all the above. I'm seeing some slow load times for some pages. Not sure what's up yet. I don't have an IPv6 address assigned, so that's probably not my issue? Also, I'm taking a stab at running this on debian on google cloud vs. my rpi. Thoughts?

Thanks!

Make sure your port 443 rejects traffic instead of dropping it.

33

Thanks for the response. Where should be be rejected specifically? For the redirects that go back to the lighttpd instances?

34

Use iptables:

iptables -A INPUT -p tcp --destination-port 443 -j REJECT

Thanks. That does make sense. However, I configured lighttpd and the admin service to use HTTPS. I have a habit of securing connectivity, especially when transmitting passwords. But I see where you're going, so I'll do some digging on options. Thanks again!

36

If port 443 isn't dropping traffic, then it should be fine.

37

I've been reading up on iptables lately, would multiple rules for 443 be beneficial?

-i is input versus -o for output?

38

I'm personally not well versed with iptables beyond the basics, so whatever fits your situation.

39

No, you specify if a rule applies for in- or output by adding it to the appropriate chain (-A INPUT or -A OUTPUT).

I was running into this issue but only on Chrome for Android specifically -- no other computer, browser, etc. -- and it hadn't happened before. I remembered I recently installed Uncomplicated Firewall onto my pihole and decided that must be the issue, and it is. I had ports 22, 53, and 80 allowed from local IPs on both UDP and TCP, and every other port was set to "deny".

Neither allowing port 443 nor rejecting port 443 fix the slow loading issue for me. The only way to fix the loading issue is to disable the firewall completely. Is there another port I should be aware of?
