What is needed for remote RSS (PEAR) to work?

[ekhoo]

I've a few servers running serendipity.
One is on my dedicated hosting server and my remote RSS plugin (1.5) works fine.
Another is a virtual server with two IP addresses and two separate instances of serendipity. Both refuse to work (plugin v1.5 and 1.7) and crap out with the following cryptic PEAR error:

Success
Notice: Success in /home/.../bundled-libs/PEAR.php on line 848
Success

Hi!

This error means that a server's firewall is blocking access on outgoing HTTP 80 ports, but that firewall does not return properly closed connections, which confuses the PEAR plugin - so even though it says "Success!" in fact, it's an error.

Best regards,
Garvin

Thanks Garvin.

For no apparent reason, it's working now. I've raised a support ticket with my hosting company and they've not done anything yet but try to understand my problem and lo, and behold, it works today!

/keeping my fingers crossed it'll continue to work
