Well, I still think it is related to the server response time and the proxy waiting time. One ends up canceling out the other, and the connection is interrupted. 

Thanks. I added those rules to mine. But same error... Same amount of images not loading

This is why I think this is not a cloudflare problem.

I already had rules which would make the same effect.

I added it in two places of the WAF rules.

Go to "Security > WAF > Tools" and add the following:

In "Custom rules" I also did this:

Here you can also add the IP. But I think the most efficient are the rules in WAF > Tools.

Now, the IP can sometimes change (rare but it can happen), so you can monitor it here: https://www.meuenderecoip.com/descobrir-ip-do-site.php

Hope this helps.


Cloudflare really isn't a practical service. It may be good and have a lot of features, but it's a bit confusing to organize. It took me a while to understand what was effective or not. Furthermore, their support is not very good, even for paying customers. At least I didn't get any kind of support. It was a lot of trial and error, based on some of their (complex) tutorials.

What is the server proxy IP? Did you add it to the WAF settings ?

 have looked in several cloudflare configurations,  and i don't think it there is much to do there.

I even added a free limit rule to all /api/* endpoints

Yeah, it might not be.
But, in reality it can deny access, due to the waiting time that the proxy has. Or it could be the proxy itself that shuts down after some time without receiving a response.

The point will be that this can happen if there are a lot of people accessing the information at the same time.

But, as I said, this is my perspective based on the analysis I can do when opening the topic in question. I could be totally wrong.




The difference is that FeeBuddy is a static image. These are dynamic images, they change each time you refresh the page.

Your example will always load, because (with my post) there are only 2 identical requests for each image, for a user.
Imagine multiplying that by 50 images, for 10 users at the same time. At the same time the proxy is asking the server for 500 different images, and the server has to generate all of them. This may take longer to do and the connection may drop.

Now, there may have been some configuration change that caused this, on the server side or on the proxy side. I can't say that anymore.
Heads up, this is just my guess.



EDIT:
I did some more tests on the topic (several refreshes) and there comes a point where it stops showing all the images, which really indicates some blockage to the image proxy.
In addition to the exception to the forum, you have to specifically give it to the proxy.

I suggest adding the ASN of the forum server to the list of provisions/executions.

No, there was no downgrade, in fact I'm thinking about some upgrade.
We can add an exception for Bitcointalk. Which is the forum IP anyway, since it goes through CF and it?

btw. I saw that FeeBuddy worked today.

Just for testing purpose

I think this is unlikely to be the case, because I can see access denied in logs (not always, but often)

Also, the server handled those requests for years. I see no reason to suddenly stop handling those requests. Unless examplens downgraded it, but he would have said as he is already in the discussion(this is a shared server).

Maybe bitcointalk.org changed something?

Have you ever thought that it might be response time to server requests?
Sometimes, when there are many requests, the server is unable to display all the data in time, before the proxy connection is disconnected for security.

When I opened the topic in question, I got this idea.
The proxy is waiting for the image, but as the server takes a long time to give, The call drops.

That's why the result is always different when you load the page.

I have noticed that it is getting blocked on this page created by Pmalek, as it makes about 50 requests.

I think   cloudflare isn't blocking it . But I don't have full access to da settings

I saw only two logs generated on 9/12 in ModSecurity and both are related to the bytespider crawler.
The Bytespider bot is affiliated with ByteDance (the company behind TikTok) and is used to index content. It is not malicious, but it is recommended to block it due to very frequent requests.

edit:
Do you have full access to the site and hosting and have you noticed any restrictions on API requests from the site?

Looks like there is a limit in DA. I checked the logs


Is there a way to withelist bitcointalk IP address from there?


Yes, but it is not getting blocked in cloudflare as far as I know.

I added a custom rule which is triggering, to unblock requests to the api:

Could it be there's a limit on the number of simultaneous connections from one IP-address?

Sorry for the late reaction, I was on a trip, and I didn't have an internet signal for a good part of the time. What exactly is happening on your end?
As far as I can see everything looks ok, there is no unusual activity. Also, the site is functional.

Hey @examplens.

I think cloudflare is letting the traffic go, but looks like DirectAdmin is blocking it (according to DA logs).

Can you take a look? I didn't see any security options in DirectAdmin page.

It seems that your custom rule fixed around 1/3 of the missing images, but most of them are still not showing up as they should. In fact, each refresh loads the site differently on my end, but a big part of the images still show the image proxy error. Is the thread loading normally on your end? I tried it in different browsers, but no change.

Thanks for pointing out.

I didnt change anything. They are working in my server, https://bitcoindata.science/bitcointalk-api

I will try to change some of my server configuration to see if cloudflare is blocking it

Edit: I added a custom rule for bitcointalk and fixed it!!

Hi bitmover,

I noticed yesterday that the images in my Withdrawal Fees and Withdrawal Amounts on Crypto Casinos thread aren't showing on the forum. Did you make any changes that might have disrupted the images on Bitcointalk or is this a forum-related problem? Have you noticed similar problems with images elsewhere?

Been using the Bulk balance checker, and it's working great. Thank you for the project

Hi @bitmover, thank you for the work done, the site is needed, important and useful. This is primarily a thank you for your work, and secondly:
page /bitcoin-units-converter



for some reason, the height on the flag is set to fixed and not auto, which slightly distorts the dimensions..

width: 26px
height: 26px (change it to auto if you want)



GL,
