This forum: 403 Forbidden ?


Since today I got

Forbidden

You don't have permission to access this resource.
Apache/2.4.18 (Ubuntu) Server at www.sciencemadness.org Port 80

Then I connected via a VPN and now it works again, so it probably looks like an IP filter. Since when is censorship op IP address implemented ?

That is not the issue. With https I also get a 403 Forbidden. It has to do with my IP address ? It is a standard EU IP address from my internet provider, there is no TOR like proxy between it.
With VPN I can also connect without https.

I am afraid only Polverone can give a definite answer to this. None of the other moderators has access at system level (as far as I know). Did the issue suddenly appear? It worked up to now from the same IP-address? Maybe you received another IP-address from your ISP? I know of some providers (e.g. Ziggo/Vodaphone in NL) who provide semi-fixed public IPv4-addresses. The address can be the same for many months, even more than a year, but suddenly, after a reboot of my modem, I get a new IP-address. Such thngs happen sometimes, when the download/uplink speed changes (e.g. either by taking another contract, or because the provider upgraded and asks/forces you to reboot the modem/router). But even if this occurred, then I still would not expect an issue with accessing sciencemadness.

I'm getting the same error now. Changing the IP helped for a day, then I was blocked again.

Is this the end? If so, where do we go?

Have you tried clearing the cache?

I have had some issues that only an empty cache or a new profile could solve. Who knows why.

Yes, it had no effect while a new IP address worked. Using a proxy also works.

I think I've found the trigger for this "feature". I was on my phone, trying to dig up the "new threads" page using Firefox's autocomplete. I accidentally tried to access "https://www.sciencemadness.org/whisper/viewthread.php" and got the 403 error again.

Funny. That link gives me "Error. The topic you have chosen does not exist."

I've got the same problem, in fact I could log in, but while making a post I got the 403 error, and no matter what I did I couldn't access the site again. I'm writing this using a VPN and an American IP adress, which did solve the issue.

In the past I had problems using the https secure connection, but I could access the forum and post when switching to http. Now that is not possible anymore, the browser forces me to https.

Strangely enough, I can access the forum on my phone using 4G, but not on my windows PC using ethernet. But both use the same internet provider.
Also, I could access the forum on PC without problems until recently. Now whatever I do, I get a 403 forbidden error, no matter what browser is used

@dicyanin: It appears to be an issue with the IP-address. Which mean that any traffic coming through your modem/router will be blocked. Your phone will have a different IP-address so it isn't affected. You need to get a new address for your router, how this is done depends on your equipment and your ISP's network settings. Some simple things to try:

Simplest: Restart the modem (power off for a minute or five). This will not work on all equipment. The pro method is to renew the network lease trough the modem software. This will require a fundamental grasp of networking lingo and might not be available on your device. Last option is to call support and ask them to renew the address.

Some ISP's use a fixed IP-address. E.g. I have KPN internet in the Netherlands, and my IP-address is fixed, so that trick will not work with such an ISP. Having a fixed IP-address is considered a good thing, so what is proposed here is not a real solution. Polverone should have a look into this for a real fix.

If it really does not work, you could take a VPN plan (e.g. NordVPN for $3 or so per month) and if you get a problem with one specific IP-address, you can switch to another server and have a new IP-address. Most VPN-companies have hundreds of servers worldwide, so you can use many IP-addresses.
Yet another option is to use a mobile phone and use tethering. Each time the phone connects to the internet it gets another IP-address. Only issue with many mobile networks is that the IP-adddress you get is an internal address (e.g. 10.x.x.x) and that the outside/public address is one from a small pool of addresses. Whether this works or not depends on your ISP, but in NL, most mobile network operators use CGNAT and don't give you a public IP-address on your phone.

Yes, this is something that only Pulverone can fix properly. But for many there are workarounds that can work. One good rule would be to only follow links and stored bookmarks on this site, as it seems to be some sort of "anti-snooping filter" in place.
