version check failed - could not connect (especially on upnp-ed networks)

hi there,

lately i get a lot of these errors in the about dialobox (win32, latest builds) on networks with upnp routers when wuala client wants to check if theres a newer build out there...

if i close logout/restart wuala it downloads the latest build anyways even if the check in the about box failed.

would be great if the checking for a new build would be more reliable (maybe other protocol, triggering it directly with a button or a url and so on....)

maybe it has also to do with congested networks (even the local lan or the gateway to the inet), or nat-overloads at the gateway or such thing.

somehow i suspect that the versioncheck is also performed by means of udp rather than a tcp check of a browsing of some url/xml/file because the failed message turns up so very quickly/instantly on the client... there seems to be no timeout or something.

thanks.
