Hello,
For some time now, it has been more and more difficult to access here on this forum. I specify that I tried on several computers, I have a very good connection, and I cleared the caches.
I wanted to point out this inconvenience.
Serge
Can you please explain more about the difficulty? Is it not responding, or very slow, or do you see error messages.
I’m not aware of others having difficulties, but if anyone else is having a problem please let me know by commenting in this thread.

He grinds and thus remains with a blank page. I noticed that in the morning.
I specify that I look at the Arduino forum which uses the same as you and there is no problem.
One difference I see is that you’re accessing the forum using IPv6. At the moment there are very few users who use IPv6. I can’t be sure that’s the problem, but with no-one else reporting a problem (so far) it’s the only obvious difference between your connection and other people.
Unfortunately I have no way to connect to the server using IPv6. My ISP has been promising that they are looking at implementing IPv6 for the last 14 years but still haven’t done anything. Something in their system also slows down at least one IPv4 to IPv6 mechanism so testing using that wouldn’t help me because there would be no way to know whether it was my ISP connection or the forum server that was causing the problem.
I’ll investigate creating an IPv4 to IPv6 proxy server to see if I can re-create your problem and maybe also gain a greater insight into how IPv6 works with my servers. That’s not going to be an immediate solution, but it’s the only one I can think of for now.
Hello
Thank you for this additional information.
Have a nice day.
Serge
Same issue here.
Clicking to go to threads just shows the loading circle
I can see the pattern emerging. You also have an IPv6 internet connection.
The servers don’t actually see IPv6. Cloudflare accepts IPv4 or IPv6 connections but translates them all to IPv4 for onward transmission to the servers. I know you’re using IPv6 because Cloudflare pass on the originating IP address in an extra field.
IPv6 shouldn’t be an issue.
I have had an IPv6 address for 5 or 6 years. The slow nature of this forum has only started happening in the last couple of weeks.
You’re right, it shouldn’t matter and hasn’t in the past. I’m just pointing out that the two people who have currently identified a problem are both using IPv6. The majority of users still using IPv4 don’t seem to be seeing the same problem.
Having thought about it, I think the problem must be somewhere upstream of the servers. As far as I know (still to 100% confirm) all traffic arriving at the servers is IPv4 and other than the special Cloudflare variable that contains the originating IP address the forum doesn’t see anything IPv6 related. The IPv6 to IPv4 ‘conversion’ takes place in Cloudflare and all traffic is then sent down an IPv4 tunnel to the server. Even if the tunnel was IPv6 it wouldn’t matter…it’s a common tunnel for all forum users and the tunnel is IP version agnostic so a problem there would affect all users.
I think I should be using IPv6, but I’m not seeing any issues.
You’re shown as using IPv4 (IP address ending in 159).
Its appears that Microsoft Edge prioritises IPv4 over IPv6 - the opposite of the Windows OS!
Interesting. I assumed Edge would just let the OS get on with networking.
Just thought I’d disable IPv6 to test, but I still get the same issue.
The forum layout loads, but when I go to a thread, it can take more than a minute to load sometimes.
i have just had this and 502 error twice in the thead part
and just to add to this i have just had a cloudfare 502 error saying host error
also a failed to load topic due to connection error
The 502 error was probably due to me updating the Cloudflare components. I don’t mention this when I’m doing it because it’s pretty quick but as you have seen it is possible to get an error mid-update.
I have a theory about what might cause some of these issues. I updated a couple of forum web interface components this evening. I’m wondering if Cloudlare is holding onto the old component too long and that confuses the server?
I’ll empty the Cloudflare cache tomorrow and try to remember to empty it after each update.
just got a 502 error as well
forum appears to be working now
I think the default cache hold time is a few hours so I would expect things to return to normal after that time.
This still doesn’t account for why some people are seeing long term problems.
