Not long ago I tried to access the forum and this came up instead:

I'm sorry to disappoint you, but I fear that Error Code 520 (which, judging by your scan, is imperforate and unwatermarked) is a transient flaw that has already been catalogued, and is too common to command a high price at auction even with full original gum.

To put it another way, I think that this kind of thing is what you get with Cloudflare, instead of the connection occasionally hanging for a while or timing out completely. It's only a problem if it happens a lot.

I see it sometimes elsewhere, but not at SCF so far.

I got one of those yesterday too. I refreshed the page and the error went away and I haven't seen it again since.

I keep getting these, too, but only on iPad which has a WiFi connection. It seems only to happen following the "I am a human" check. Do you also find that that check takes a long time to present? I had a record 2+ minutes this morning, then I hung up on it (on my iPad),

On my Mac with Ethernet connection, SCF comes up immediately and allows me to be logged on at the same time using both Safari and Firefox without the human test.

So perhaps the human test only comes up on a mobile device.

I'll do a test today to see SCF performs as well on Safari and Firefox when it is connected vie WiFi.

I use Chrome on a laptop using wifi, and get these host errror pages every now and then. Lately, they have been popping up much more frequently than before, Refreshing the page solves the issue. However, they pop up after I logged on. The Cloudflare check pops up every time I open the SCF page. Sometimes it is a bit slow, but then it takes 10 to 20 seconds. A couple of seconds is normal.

That is the same as I experienced. Closing down an SCF page on my iPad on WiFi caused a log out.

They will happen occasionally. I have never gotten that error where a page refresh didn't work immediately.

The alternative is that we let the 60,000 bots roam freely and bring the entire server to its knees.

In the last 24 hours, less than 2% of the requests hitting the server were human.

Edit, worded that wrong:

Dropping the Ethernet and running the desktop on WiFi made no difference. SCF came up immediately with no delay and no human check.

It would be interesting to hear from people with an indication of:

- whether you use a desktop, a laptop, a tablet or a smart phone, and

- whether or not you get the human test, and

- whether or not you get logged out if you drop the connection to SCF, and

- whether you use Ethernet or WiFi.

90% of it is IPA reputation and has nothing to do with devices/hardware.

It also has to do with ASNs, browsers, packet inspection (TLS/HTTP fingerprints), and behavior analysis such as mouse movements.

I use Chrome


Chrome with google for searches is probably the worst combination if you don't want Google peering into every aspect of your life. It is probably even worse if you use the gmail service and/or the Gmail app.

I have started using DuckDuckGo as my browser. I have also installed their extensions on Firefox and Safari. The DuckDuckGo browser seems, with my somewhat limited experience, to work well and fast - and is totally divorced from Google. Firefox and Safari both use Google as the search agent by default but add the DuckDuckGo extension and change it to the default search engine and your separation is greatly increased.

It is available for both Windows and MacOS.

It is Yahoo! and it is terrible. It cannot find the Atlantic Ocean if it is drowning in it. At the office, it is Edge with Bing. That is not much better. When I really want to find something, Google still gets the best results.

I've been blocked from this site by Cloudflare for months due to that javascript and cookies problem. Looks like they did not notice I snuck in today. Any hope that will get fixed for good? The Coin forum is experiencing the same trouble. Cloudflare may go back to blocking which means it's unlikely I'll be able to see a reply.
