    hi,

    my iMessage doesn't work when i am connected to my office network. i understand there might be some port/firewall setup by our network admin. but is there any work around?

    The ports are probably blocked. However, you might want to try connection doctor by selecting Video > Connection Doctor to assist you with possible connection issues

    Probably firewall restriction. Mot large companies, mine included block ports not deemed business essential. Many of these would fit that description

    How would we know your office network setup?
    And just use your smartphones personal hotspot if you want to use imessage so bad.

    These are the ports that FaceTime uses, they might be the same for iMessage, they might be different.

    TCP: 80, 443, 53, 4080, 5223

    UDP: 16393 to 16472

    Per John @ Apple.

    Many places will block everything outbound except for ports 80 and 443 (regular web traffic). If that's the case, you're probably stuck unless you can get them to open up the ports.

    iMessage works on my school network, and they block pretty much everything, so....

    Even SSH doesn't work on my school's network!

    The OP to the best of our knowledge does not attend your school so that does not help.

    iMessage needs ports 80(TCP), 443(TCP) and 5223(TCP) in order to work. It is most likely that HIS network is blocking port 5223 as ports 80 and 443 are generally left open.

    I'm at school and I just ran a port tester. Ports 443, 80, and 5223 are all blocked... So I'm not sure how the network works here.
