pcper.com down? [mostly solved]

[EDITED: Solved, see post further down.]

Is anyone having trouble reaching pcper.com? I get redirected to 127.0.0.1 when I try to go to their site. I wonder if I tripped some kind of content or spam filter.

Does anyone have a contact there who can look into it?

Works for me, redirect to localhost could be something on your end.

Thanks, I tried isitdown and it showed it okay, but I don't know what they do to check if something is up. I can ping it, but any reference to it in my web browser (FF) goes to localhost.

I did just try wget on it and it got the index.html and it looks normal. Wonder what FF did to get so confused?

Solved. Don't know what happened, but it looks like FF has its own DNS cache and it got corrupted somehow. The way to solve it was to go to View History->right click on pcper.com and select "forget this site". Then everything was fine. (so far).

Thanks everyone!

Even more followup. I am now logged out--I assume 'forget about this site' also kills cookies. No problem, hit the "login to reply" button and......127.0.0.1. Forgetting the site doesn't help. Looks like there might still be something on their end?

Who do you use for DNS?

The site works for me. Try another browser to see if it's a FF issue or something global to your computer or LAN.

My ISP. The thing is it's the same hostname, so DNS shouldn't really be playing a role at that point.

Can anyone reproduce? Do the 'forget this site' thing and then go to a story with comments and click on the "login to reply" button?

I don't have another browser, but I did try it on FF on my cell phone (Android) and it shows the same issue. It goes to 127.0.0.1 when trying to follow the login link.

EDITED: I take it back, I have a ChromeBook handy..... It shows the same behavior.
EDITED2: Okay, tried the login page specifically with wget and:
$ wget https://pcper.com/user-login/
--2019-06-27 11:06:27--  https://pcper.com/user-login/
Resolving pcper.com (pcper.com)... 104.200.29.114

Strange. Looks like a 302 problem? I get to the login page just fine, and there's no 302, only 200.
Try on your phone to connect thru the cell network rather than WiFi.

And not that it looks like the problem, but for good measure try also other DNS servers, like 1.1.1.1 or 8.8.8.8 or 9.9.9.9.

Yeah, stranger and stranger. I told FF to forget the site and changed the NS to 8.8.8.8, went to the page and got the same redirect.
wget does the same thing.

But, the cell phone using FF and mobile data works....

What is going on....

Thanks for you help, by the way, it's greatly appreciated.

Are there any web/ad blocking rules on your router?

Tried power cycling the router?

On my Ubuntu box it's sometimes necessary to flush the DNS cache from the system also with systemd-resolve for changes in DNS entries to take immediate effect. I'm assuming you're using Windows, so maybe that has something similar?

Fedora 29 here, FWIW. I'll look to see if they config systemd similarly.

@meerkt, nope, router just moves packets, it doesn't do any filtering other than dropping incoming connection requests. No pi-hole like stuff at all.

I'll try flushing the system level DNS and see if that helps.

Nope, that didn't do it. *sigh* I'm waiting for my forum membership over there to get out of moderation. Once it does, I'll ask them if there's something it might be.
