Forum Breaks/Bans My IP When Trying To Visit Old Post?

Clyde

I can confirm it, too. After loading the link, I couldn't connect to any page on retropie.org.uk anymore. A new IP fixed it again.

@Clyde, @YFZdude Just trying to gather further data that may be helpfull in pinpointing the culprit within that thread -> as opening just the page that opens for me via the link hasn't provoked any bad side-effects, but opening page one of the thread did: In what mode are you two viewing forums threads? Paginated or "infinite scroll" ? And if it was on infinite, have you tried to scroll upward (back in time) or did the ban happened just by opening the link?

Clyde

@Ashpool Infinite scrolling, and the effect occured right after visiting the link without any scrolling.

@Clyde Thanks...

I've tried again and this time I was "disconnected" from retropie.org.uk in an instant :( Sorry that I jumped to conclusions due to my previous experience. Now I am really unsure why I was able to "stay alive" in the forum until the time I've changed "pages" - I had multiple tabs open for the retropie address (If it would have been old times & me using Opera Presto that may have been due to that aggressive cache/history policy fooling my observation, but nowadays its firefox/vivaldi I am using) and am really flabbergasted now! [Edit: been back in less then 30 minutes, due to shutting down the router and obtaining a new ip on [~5minute deleayed] restart]

@Ashpool
Thanks for the protip. Using your advice I was able to get the temp ban.

I scroll but when I jumped to the top post with the arrows I can only go about 20 posts before it has to load more posts. About the third load it got me. I think it has something to do with requesting too many image loads in a short span of time or something. Coupled with the fact that old images aren't showing correctly might be doing it.

Sorry about that.

It's the protection I have in place to limit connections (due to bad bots etc). If the connection limits are hit too often in a period of time, the IP will be firewalled for 30 mins.

I couldn't trigger it from normal use when I configured it but maybe it's possible to trigger due to forum software changes (or the number of images on that thread).

I will disable it for now. I may be able to change the config to make it ignore static data. It's more for restricting bad bots from hogging all the nodebb connections and slowing the forum down.

[edit] Static content should bypass it anyway but perhaps it's due to the fact the images are missing that it passes the connection on to nodebb and triggers it.

[edit] It was caused by the fact the images were missing, which caused the connections to be proxied on to nodebb (which the connection limits apply to).

I will see if I can sort out the missing images. I looked into this recently and had to regenerate thumbnails due to a nodebb forum bug, but perhaps I missed some or it's been triggered again.

@obsidianspider I have restored the images from an old backup. If you notice any other posts with missing images, please let me know. Thanks for the heads up regarding the issues.

Clyde

@BuZz Thanks for looking into it that quickly!

@BuZz Thanks so much for your help in fixing this.

Also, thanks to everyone else who tried to troubleshoot the issue. I realize I'm not active on here much lately, but the way this problem was handled is an amazing reminder of how this a really excellent community.
