Website I can no longer access - a user Forum - why?

OK, wonder what is going on.  Resetting the modem by disconnecting it form power makes no difference.  I can access the forum fine outside of Hughes Sat connection.  Wonder why?

 

http://www.haiku-os.org/forum

 

Can someone else see if they can connect please.

 

I get the following error message when I try from multiple systems, Mac, Linux, iOS, etc....  using various browsers.  All the same issue.

Cannot load app

It looks like you are offline! Please check your network connection and try again.

 

Regards

TJ

I am going to reboot the modem and this system again and try once more.

No go.

Reboot Hughes modem... Reboot Ubuntu system.... Emptied cach (full empty) of Chrome browser.... still can't access the https://discuss.haiku-us.org

 

This site can’t be reached

The connection was reset.

Try:

ERR_CONNECTION_RESET

That's just weird.

 

So, what we've determined is that there is something messing with your ability to resolve DNS to at least a couple of things. There's nothing else wrong with accessing directly via IP.

 

Just hunch, and realize it's probably a pita, but try going back to automatic DNS and rebooting/clearing everything. Before you bring up a Chrome browser or another application (if possible, some things kick off automatically), try doing a ping and/or traceroute like you did before using name, not the IP address, to see if it resolves.

 

I'm concerned something is running that is either blocking or rerouting your DNS lookups.

Had already left DNS on auto. Cleared browser cache. Turned off main linux system. Reset modem.  Turned system on.  Went right to Terminal.

 

tj@Maingear:~$ traceroute https://discuss.haiku-os.org
traceroute: unknown host
tj@Maingear:~$ ping https://discuss.haiku-os.org
ping: unknown host https://discuss.haiku-os.org
tj@Maingear:~$

 

Add some more oddity to this... So I have MANY computers... Normally connecting via Mac Mini, Ubuntu on Maingear PC, two iPhones, 2 iPads, and an NG Amiga.  Yes Amiga.  😉

 

Guess what... with the Amiga OS 4.1 system I can access the https://discuss.haiku-os.org fine.

Don't recall if I ever did prior... but it works right now.  It is wired direct to the Hughes Router.

 

ALL other systems that I have connected to Haiku-OS Discussion forum still do not connect.  Did for years.  All I have erased cache.... and tried all versions of browsers.

 

Linux box is direct connect to Hughes router.  Rest via wifi.

 

Makes weird sense one antiquated in modern terms Amiga OS Odyssey browser works though.

It seems odd, but the way local DNSes propagate across a local network first it's very possible that any one of those devices was contributing to a corrupted lookup and just feeding it back.

 

Hopefully you've found the culprit and squashed it for this as well as the other site issue.

 

Edit, before I forget: When not in automatic IPv6, I've generally set my DNSes to look at 192.168.0.1 first, 8.8.8.8 second, and 8.8.4.4 third. For some reason that seems to lower the possibility of that happening.

Is there a way to flush the router of any cached web urls it is storing, if it is doing that.

Just seems weird all systems other than 1 oddball system I may not have visited the Haiku forum before works yet all these others do not.

I would think only the Hughes Router is allow DNS access and allowing various computers to visit sites.

Are you saying other systems like my Mac Mini or iOS devices are interfering with that and maybe all systems are getting the DNS from it instead?

TJ

I'm saying it's possible, and even more convoluted than you think.

Could be an instance where it got currupted on one device, and another deivce just happened to pick up the bad lookup for safe keeping, then repropagated it the next time any other device tried to go there.

 

If that's the case:

1. I'd switch everything to point to the modem DNS (automatic).

2. Then power everything down with the modem being last.

3. Then, power everything back up, modem being first to own the master DNS, with everything else following afterwards.

4. If you want to change the DNS on each device to point to something else after that do so.

 

This way you be assured that any corrupt entry is completely expunged from your local network.

Cool, thanks.

Business to attend to and a business trip so will have to try that when I get back.

Just need to get work done now.  hah.

Thanks for the help.  It is for sure an odd one.

Good morning macsociety,

 

Welcome back! Thanks for posting, that sounds odd, so I really appreciate you letting me know what troubleshooting steps you've tried. I can access those URLs from our Gen 5 system here with no issue. 

 

Was Saturday the first time you noticed having difficulty visiting that site?

 

I've cleared your DNS cache from my end, please let me know if that makes a difference.

 

If you're still getting that "Cannot load app - It looks like you are offline! Please check your network connection and try again." error, temporarily disable Web Acceleration and let me know if that makes a difference. Enter 192.168.0.1 in your browser then follow the steps here to find where to toggle Web Acceleration.

 

Looking forward to hearing back.

 


Hi @Liz, same error message as before.

Also disabled web acceleration but get same error.

I would say this started about 3 weeks ago....  I used to frequent this site and seem to remember seeing the error 2 to maybe 3 weeks ago is my best guess.
