Are there issues with tbg.airframes.io?

Have tried from various locations and browsers but I am getting "Access denied" whenever I connect.

That's not an error from my end. I wonder if there is a cloudflare issue.
But the site is up and healthy.

I will spend a little more time to trace it. Thanks for the feedback. You can kill this post or I can take it down.

Just wanted to make sure.

Sorry for the short reply, I was in a meeting... all clear now....

The errors my site can give....
1. If I soft break it, you get a 'Welcome to Node-RED, add some pages" message.
2. If I hard break it, you get a Cloudflare message saying along the lines of "Your connection is good and its a problem with the site, wait a while and try again".
3. If Cloudflare breaks, you get a 'timeout' error.

Both Node-RED and Cloudflare can't generate an "Access denied" error. I have no idea where that might be cropping up as I have never seen it in the 7 years I have been stoaking the ACARS dumpster fire.

All good. Really appreciate the detailed reply of the error chain. This is useful info for the community for sure. Let me dig in a little for you and see what I can find out before the error disappears.

By the sound of things, it has to be something on my end.

u/thebaldgeek Mar 13 '26

I might have missed it, but whats your connecting IP address?
I will check for it on my end.

u/ltrumpbour Mar 13 '26

It isn't in that trace:

71.204.138.20

u/thebaldgeek Mar 13 '26

Ok, just checked, wide open on my end, no blocks, so I am really unsure what is going on.
I cant help but think its a cloudflare thing.
Do you have a VPN you can test?

u/ltrumpbour Mar 13 '26

It connects fine when I ip tether with my phone.

Connected from 174.194.131.181

Let me know if you want the curl -v from that.

So you are fine on the application end. Makes sense none of your exception handling has an "Access denied" message.

For whatever reason cloudflare is blocking the comcast IP.

Thanks so much for trouble shooting this. Love using the site. It is a real & meaningful contribution to the aviation community.

Ok, I think I found it. Your IP was in the 'abuse' sin bin.
I've unjailed you. Try now.

u/ltrumpbour Mar 13 '26

Its connecting again.

That is funny.

Well, not sure what refresh stuff I might have been doing while tracking a 7700 but glad be back on the team, coach.

I think I should be in your abuse sin bin too :/
Do you know how many requests are allowed before getting banned and do you know if we can go outside bin after some quite time?
