I installed BOINC and get "communication deferred" all the time; I suspect my hardware firewall is to blame. What port does BOINC use for communication? If it is standard HTTP port 80, there should be no problem there and the cause is something else.

There are selections for HTTP and UTP traffic in my router, all disabled by default (a Good Thing), but some software (maybe BOINC?) demand I open a port for them manually, so I suspect that's the case here.

Ports for V5.4.9

boinc.exe needs internet access on ports 80 and 443 and local access (127.0.0.1) on ports 31416.
boincmgr.exe, boinccmd.exe and boinc.scr need local access on ports 31416.

Yeah, why is it that basically every time I hit update it comes back with "communication deferred" (I just hit retry communications, and sometimes it works sometimes it doesn't).

Am I supposed to be getting "communication deferred" (I mean are the servers THAT busy that they always tell my machine to back off for 10 minutes), or does that signal a communication problem with the server?

It happens on my home machine, my work machine, etc. They're mostly XP SP 2 (home & pro). Probably have windows firewall turned on, but I've never gotten a pop-up asking whether or not to allow traffic or whatever. So, I assume all is working?

Like I said, I just hit retry communications and more often than not it works the second time?

It's a built in safety precaution into BOINC, so you can't "SPAM" or DDoS the project servers. Else each time you hit Update you contact the scheduler server. Now think of you and 9 other people doing this constantly for an hour. No one else would be able to get through.

So there is a deferral time built in in BOINC. If you hit Update again within 10 minutes, you are deferred until the countdown timer is at zero.
