IMPORTANT: Update to Mumble 1.2.3a

Due to an expiring certificate no Mumble 1.2.2 or newer released before today (15.01.2012) will work on the Windows Platform after 15 January 2012 11:36:47 GMT. If such an outdated Mumble is launched after that date the error message “A referral was returned by the server” will be displayed by Windows and Mumble will not start.

You can get fixed installers from from our project page.

You can get the fixed Mumble 1.2.3a stable installer from: (uninstall 1.2.3 stable first).
An updated installer for the snapshot version is available from:
You can also download a fixed Mumble.exe for the 1.2.3 stable from:

We are sorry for the inconvenience this may cause. We will follow up with a more detailed explanation later.

    no matter how many how many times i attempt to download and install the correct version i keep getting 1.2.3a installer and 1.1x actual application. *on vista*

      Not sure I understand what the problem is. The 1.2.3a installer contains 1.1.X. The two have two separate start menu entries. And 1.2.3a is the correct installer (even if the application itself says it is 1.2.3).

    I followed all the instructions and it still will not work. I just installed 1.2.3a for the first time today. My clock is right. I Can’t get rid of this error, “A referral was returned by the server” I uninstalled and reinstalled, no change. running windows 7 64 bit.

    I’m getting this error as well. Just started today, I haven’t changed any settings and Mumble was working fine before. I tried installing the certificate manually still getting the error.

    Windows 7 64bit

      Did you check your system time? If your clock is off by too much the signature might fail to validate. If it still doesn’t work our forums or IRC would be a good place to get more help.

    I’ve tried to download and install the correct version several times but whenever i try to launch mumble i get “a referral was returned from the server”…

    I haven’t had any trouble with any other Mumble versions, but certain people sound terrible with the newest Mumble. Their voices constantly crack and it is unbearable to listen to. I hope a new version comes out soon1

    I am receiving an error “A referral was returned from the server” and i’m using windows 8 currently. I was working just fine two days ago and now the program won’t even open. However, mumble backwards still opens but won’t connect, and normal mummble won’t even open at all. Any help would be appreciated

    There has to be a way to permanently disable this crap. What about those of us who don’t have to keep up with the Jones’s (keep up to date), like myself. I always say, if it ain’t broke, don’t fix it!

    I’m sure some people appreciate the ‘upgrades’ and ‘bug fixes’ of constantly updating, but I for one would like to just pick a decent working version and stick with it!

    Looks like in order to do this I’d have to go back to v 1.2.1 (I also do NOT like how if you untick to check for updates in 1.2.3+ it automatically re ticks it any **** ways!)

    Cmon, I really like Mumble over any other commonly used VoIP (for gaming especially), but this is the ONE aspect that is KILLING me! PLEASE make it so that we don’t have to worry about this stupid cert error if we CHOSE to run an outdated version. And PLEASE make it so that if you untick “check for updates on startup” it ACTUALLY STAYS that way!!!

    For what it’s worth, that’s my .02
