XF 2.1 URL unfurling problem

[Robru]

External links work fine, but with internal forum links I get this error.
What should I do and where to keep the internal links working properly?

Thank you.

It's most likely an internal DNS resolving or firewall issue. It's not uncommon for a web server to be unable to resolve its own domain name back to itself (or firewall configured to block its external interface).

Are there any errors in the server error log?

Thanks Chris, I will check the internal DNS resolving and the Sophos firewall or that it will not block the external interface.

You mean de apache2 log?

 

[Chris D]

Disregard that and focus on the advice I've given you. There's unlikely to be any relevant logs at the PHP or web server level.

Ok, thank you Chris

I am also having a new problem with unfurling. External sites unfurl and display fine, but when posts on my forum are referenced, I get the following 403 error (via the Unfurling tester). The URL just shows as the plain URL (as if it was pasted on the same line, not a line by itself for unfurling purposes).



Has anyone had this problem and would they know why? It was working fine until recently.

Thanks
Gerry

Is the forum/post in question open to guests?

Thanks @ozzy47 ! That seems to be the issue. The unfurl tester is showing this now:

I'm order for the unfurl to work, the link must be viewable by guests, that also includes internal ones.

It was working before, so I'm not sure what changed the permission for guests. Weird.
