XF 1.5 403 response when posting a link on facebook

[AzzidReign]

When we post a link to facebook, the preview shows up as a 403 response. If you go to this debug link, it shows the same. Seems to do that on all pages besides robots.txt so it seems it may be something in the code?? I've been messing with this for a couple weeks now with no solution. Hoping someone smart here can tell me what is going on and why we are showing as a 403 for the preview but people can still access the site (se7ensins.com).

Is the page visible to guests?

It's looking like a web server-generated error, so it's probably at a level above XF. It could be user agent or IP based blocking, for example.

Thanks, my server guys kept blaming it on my scripts but since it was occurring on a wordpress install for another site I have on my server and my main site, I kept pestering them. They finally found that there was a *php* bot (idk?) that was blocked during a flood and it ended up effecting fb bot. Thanks for the replies...I was just trying to turn to anyone that knows more than I do on this stuff and I knew it had to be on the server end but really through me for a loop when it was able to fetch the sitemap.txt and nothing else which made me second guess where the block could be coming from.

To answer this question, yes, guests were able to see the pages I was having fb bot fetch. I would view the site through incognito since I also thought maybe it was a permission we screwed up along the way.
