Transport Tycoon Forums

Possibly related to the SSL-ation of the forum a while back, but that thread is now locked.

My signature has reverted back to its bugged version back when the SSL stuff was introduced. I've checked the BBCode, and its still correctly set so the BBCode has not gone awry - however the signature image doesn't show (and i've checked, the image is still being produced correctly) If you go to the image link produced by the forum, it gives a 502 Bad Gateway.

I have noticed the same error appears in Emperor Jakes signature, noticed on the last post of the SSL thread here.

Has something been rolled back relating to the fix you did in the past Owen?

Hmm, I think I had to manually replace the version of the camo image proxy being used - maybe it's been reverted. I'll need to check.

That said, your signature looks fine to me!

I can't see the image in Redirect Left's signature. Running Google Chrome on Windows 10 (14986).

Same for more signature images, including mine.

I can see my own signature photo, but not those of Redirect and Hyro.

I can see yours, but not mine.

/OK, now it's back again!

Images should be working again now; the SSL proxy was down it seems.

If you've got signature images hosted on TT-Forums, you can change the [img] tags to reference https://www.tt-forums.net/. Likewise, users.tt-forums.net is available over SSL too (https://users.tt-forums.net/whatever).

All working again now, at least for me.
Hopefully the SSL proxy will remain stable?

Hopefully; it was up for a few months quite happily. Not sure why it fell over. Sorry about that!

It seems the problem is back? My signature is empty of pictures...

And I can't link to pictures in the post, either?

Indeed, seems to be back, I can't see Anders', Leftie's or Hyro's, but I can see Chrill's.

I'm using Chrome, I don't know if that makes a difference as to whether it would work or not.

Yup. It's been gone again for about 2-3 days that i have noticed.

I'm using Firefox, so i don't think so. Also same on my phone, which uses a mobile version of Chrome.

It's the issue with the SSL certificate for imageproxy.tt-forums.net - it expired on 12 Feb.

Yes, the problem has returned for me. Once more I can see my own signature but many others are missing.

Blargh, I updated the SSL certificate for the main web server, but totally forgot about imageproxy. Sorry!

EDIT: Or rather, it seems nginx just hadn't been restarted...

Yup. It seems to all be functional again, cheers!

Having a new issue.

The proxy seems to be caching things, and not looking for an updated image. This has broken my signature. It's currently stuck at one from a while ago.

The latest version of the image is here; http://thefoxbox.xyz/last_train/out.php - however the signature has not updated and is currently displaying one from a while ago.

I've tried this on two computers, and one Raspberry Pi that had no previous contact with this forum to have any cached version of the signature. So i'm fairly sure its the actual proxy caching things and not displaying the new version.

Yes, it is caching stuff now, to save bandwidth and to speed things up. It should respect HTTP cache-control headers though. It looks like your signature sends the following HTTP headers:

HTTP/1.1 200 OK
Date: Fri, 21 Apr 2017 09:14:11 GMT
Server: Apache/2.2.22 (Debian)
X-Powered-By: PHP/5.4.45-0+deb7u7
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: image/png

but doesn't include anything to say "don't cache me". Try sticking:

Header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
Header("Cache-Control: post-check=0, pre-check=0", false);
Header("Pragma: no-cache");

into your PHP script, before you write anything else. That should tell the proxy not to cache it.

On an image side of things, is Chrill's Avatar not working for anyone else, or is he just trolling us all by changing it to the file not loading type thing?

Chrill's image is working fine.
