checkmyip.com causing ddns plugin to update wrong IP

I have issue with ddns caused by checkmyip.com resolving my external IP incorrectly (and randomly) making my services not working correctly :(

Here is example log:

Code: Select all

I didn't find any contact method to checkmyip.com support to notify them about that issue.
Can you please check if that website is working correctly for anyone of you (I've tested it from several different networks in Poland and it's wrong all the time)?

If it will be incorrect is it possible to disable that one website from ddns plugin?

https://checkmyip.com/ says my IP is: 148.252.129.80 but my IP is NOT. There's really a mistake.

This page displays my IP correctly: http://www.mojeip.cz/

Thanks for checking, at-least i know it's an issue with the website.

Now any idea how to configure ddns not to use this one?

I don't know if it helps, but you can try.
ddns probably has more resources to detect IP, so it will be enough to temporarily disable the detector domain.

EDIT4: There was one more thing I thought. Why suggest an IP address when I can suggest a local domain - it might be better.

Edit /etc/dnsmasq.conf and add a line:

Code: Select all

local=/checkmyip.com/
and restart the router.
Then, when the service is fixed, just delete the line and restart the router.

Procedure for less experienced users, via GUI:
1. If you do not yet, install "Webshell for Gargoyle" plugin
2. if you want to apply a temporary solution, run the command in the plugin:

Code: Select all

echo "local=/checkmyip.com/" >> /etc/dnsmasq.conf && /etc/init.d/dnsmasq restart
3. if you want to cancel the temporary solution, run the command in the plugin:

Code: Select all

sed -i "/checkmyip.com/d" /etc/dnsmasq.conf && /etc/init.d/dnsmasq restart

Checked! Looks normal on my end. Do you have a dynamic internet connection?

It’s showing me as the wrong IP (and not even in the same country) so something is wrong.
I prefer the above temporary workaround from Roman for now instead of removing it entirely. I’d like the opportunity for them to correct their issue rather than reduce the number of available lookups.
If it is still giving bad results in 1 months time I’ll look to remove it.

I had this problem after the latest build was installed (with settings preserved). Even when I thought I'd fixed it it came back. I fixed it by disabling the TOR client (enabled per client) rebooting and then reenabling TOR by client. Somehow this seemed to be sending out requests randomly over TOR instead of directly. Mine has worked fine ever since. Might be a different issue but seems a bit of a coincidence

I never save my settings so it was flashed twice (after i noticed something is wrong) and configured from scratch ;)
