Symbiosis

In the process of locating and offering to buy on csgoempire, my program is unexpectedly closing in an average of 30 minutes, giving much less offers on the listed items (same as a friend's list). I tested 3 different types of internet connection and none proved to be effective, is this usually related to the internet connection? I'm not very experienced with the files so if you can point me to a repair guide or log, I'd be grateful.
