Dynamic DNS (DDNS) fails to obtain public IP
-
I found a solution on Reddit, it's to disable gateway monitoring (or in my case, I changed the monitoring IP):

@ManiacDC So your gateway was offline.. Or the gateway/monitor you were pointing to was not answering so pfsense thought it was offline. But it wasn't and was working.
It showed it in the gateway widget as offline? That is a pretty significant piece of info to know.. That was never mentioned here.

@johnpoz the gateway ip address does not respond to pings, so it was showing as offline in the widget. If I change the IP to something I can ping, like 8.8.8.8, then everything starts working. I don't know what's new with 2.8.0 to change this behavior:
Did monitoring change in 2.8.0?
Did DDNS updates start checking the gateway status in 2.8.0?
I don't know if my gateway showed as offline in 2.7.X, I never checked. I doubt my gateway's ability to respond to pings has changed. -
Seems to be an xfinity thing (which is my provider):

https://www.reddit.com/r/PFSENSE/comments/u9ogdh/comcast_gateway_became_unpingable/I can only presume 2.8.0 started checking the gateway status before updating ddns.

@ManiacDC You have a completely different issue. For me, it was only cloudflare that stopped working; other DDNS providers updated fine (I did not mention this though).
It seems you found a solution and @johnpoz pointed you in the right direction. It's indeed recent xfinity issue where you can no longer ping the gateway. I brought this up a couple of months ago here. Just ping something else, and if you receive a response it implies that the gateway is working.

@revengineer yeah my issue is different from yours than, but we actually don't know if @70tas 's is. They are using xfinity also so it could be the same issue as mine.

@ManiacDC Sorry, I missed the thread.
I do use Comcast, but I don't think it has anything to do with it. I think I may have inadvertently, somehow contaminated my DDNS configuration when I changed my WAN port.
I am using a script that I was given, and used Claude to help modify it so it would not update my DDNS at Cloudflare if my address has not changed, and it is working just fine.
I added the script in cron and I'm running it every fifteen minutes, but I haven't had my address change yet. Hopefully when the address changes, the script will do it's job and change Cloudflare.I've chased my tail around trying to figure out what happened, but since I have a work-around, I'm not that worried about it.

@70tas so to confirm, your gateway is not reporting offline?
