RT-N66U blocking website and missing icons in new Firmware 380.69_2 (Merlin)

[Ametz]

I have a big problem, somehow my router is blocking a website (seen like 2-3 sites that's been blocked the same way even with my phone wifi via the router its blocked) and i dont know why.

Depending on what browser i use i get:

• Windows could not automatically detect this network's proxy settings
  
  
• This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

So i did what anyone would, updated to latest firmware (RT-N66U_380.67_0) after i updated it said there was a newer update again (icons worked then) (I found out the mirror site did not have the latest firmware then) so i upgraded directly again to latest from tha main download site (380.69_2). But then all icons disappeared in the web UI

And i still can't access that website from any PC (Many browsers) or via phone (WIFI via Router but on cellular it works)

Have you tried doing a factory reset followed by a manual reconfigure?

 

[Ametz]

Why? everthing else works. I really dont think this is that kind of a problem.

Why? everthing else works.

It could be some corrupted NVRAM settings.

It would take hardly any time to save a backup of your current settings followed by a factory reset and basic setup to see if that fixes your issue. If it doesn't make any difference then reload your saved settings and you're back to where you were.

380.68 (18-Aug-2017)
- IMPORTANT: due to major webui changes, you will need to either flush your browser cache, or force it to reload the page (shift-reload) the first time you access the webui after upgrading to 380.68.

Thank that worked for the icons.
But i still can't access that website yet =P

Sounds like your ISP is blocking those addresses since they can be reached over the cellular network.

 

[Ametz]

That might be true. I cant access any of their domains:

www.myheritage.se
www.myheritage.com
www.myheritage.fi
www.myheritage.no
www.myheritage.dk
etc, i cant access anyone at all at my home.

But i can ping it and make a traceroute:

If i try to enter their website with their ip only (not url) i get yet another error message:

45.60.13.42 -
Resolving failed

Error code 22
The proxy failed to resolve site from host name, if this site was recently added please allow a few minutes before trying again.

Update:
There is a lot of websites that is blocked it seems, but it seems to only be secure (htpps) websites (Not all https tho, only very few of them). And When i use an cable directly into the wall it works perfectly, but not thru the router.

Even "COMODO internet security premium 10" can't update its virus list and i can't even access their help forums like this one: https://help.comodo.com/topic-155-1-282-2896-.html

This site can’t be reached
The connection was reset.

Given that no one else has reported this issue it seems likely this is nothing to do with the router, unless you have installed some custom software (like ad-blocking) that you haven't told us about.

Going directly to the IP address might have given use a clue:

Clicking on that link takes us to this page:

So it looks like there is a CDN between you and the site. I suggest you talk to your ISP.

As i said:

Yes I saw that. But, like I said, no one else has reported this issue. When you plug your computer directly into the wall the MAC address presented to your ISP will be different. So it's likely that you're getting a different IP address. Can you compare your WAN IP address in both configurations?

 

[Ametz]

One strange thing is that the link i started this with:
www.myheritage.se
www.myheritage.com
www.myheritage.fi
www.myheritage.no
www.myheritage.dk

I can now now access them all thru the router, no problem at all, before no one.
But now my virus program can't update it's virus definition list and some other websites (1 of 20) is blocked.

Mystery seems to be solved!

Everything seems to work as it should now.

When i changed (WAN):
UPNP: Allowed internal port range:
1024 - 65535
To
1 - 65535

My Antivirus could update, and all those websites that was blocked before is accessible again.
