    Hello everyone :)

    Whenever I try connecting to any Mumble servers I get the "Server connection
    failed: The remote host closed the connection." and "Mumble failed to retrieve
    version information from the central server." errors.

    I've googled and tried EVERYTHING including:

    • making new certificates,
    • using a different nickname,
    • disabling both my anti-virus and firewalls,
    • deleting everything (including client database) and re-installing multiple times,
    • even formatting my hard drive and re-installing

    but none of these helped and I cannot find out what the problem is, any help
    would be appreciated :)

    Try enabling TCP-only-mode in the settings, and see if that helps.

    That Mumble even fails to check for version is strange.
    Are you sure you don’t have a hardware firewall that blocks things, like in
    your router? Or connect via proxy to the internet, which is not configured for
    Mumble?

    How do I check if I have a firewall on my router?

    In your routers specs, handbook and/or configuration-interface.

    Did you try TCP-only-mode, as I suggested?

    Yup I tried that, didn't make a difference :(
    And I've tried disabling all the firewalls, makes no difference as well..

    Can you ping the server you try to connect to?
    Can you ping mumble.info?
    Can you visit mumble.info in your browser?

    Do you have a server with which you could try connecting to a mumble server on
    port 80 (or another port you know is open and works with other applications)?

    I can ping mumble.info and the server I am trying to connect to, but I can't
    go to mumble.info on my browser, what does that mean?

    That HTTP/HTTPS traffic is probably blocked. Are you in a restricted network
    or something?
    What do you get when you open mumble.info? It should redirect to
    mumble.sourceforge.net.

    The version information is (probably, not 100% sure) taken from mumble.info,
    as well as the public server list.
    It does so by HTTP(S).

    As for connecting to a server itself, as even the standard HTTP port(s) seem
    blocked, others are probably as well - like the server port.

    When I try to visit mumble.info I get

    "This web page is not available
    The connection to mumble.info was interrupted."

    Is there anyway to know for sure if certain ports are blocked and if so is
    there a way to unblock them?

    You and/or your network admin should know.
    It entirely depends on your networks setup and hierarchical architecture.

    The most typical personal environment - around here at least - is a local home
    network with a router logging in to the internet, and sharing the connection
    to the local network.
    Here, the router would be the only potentially restrictive part, with a
    hardware or software firewall. It may block ip-ranges and/or domain names,
    and/or specific ports - or all ports and only allow specific ones.

    Oh god.. I think my ISP may have blocked some ports without me knowing then

    I've had exactly the same experience here in the UAE, and apparently it's
    because my ISP blocks mumble for some reason. I found a solution on a gamers
    forum:
    Go to Mumble>configure>network, then select proxy server http(s) and enter
    195.229.241.174 port 8080

    It works, I couldn't believe it. BUT I have absolutely no idea what exactly
    that all means or whether it's safe, if anyone knows please tell me, thanks.
