  • Lost connection with server

    For about two days now, the bbm application has refused to launch. It has been writing lost connection with server....can any one please help! It's really urgent

    Hi and Welcome to the Community!
    With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (step should result in a message coming to your BB...please wait for that before proceeding to the next step):
    1) Register HRT
    KB00510 How to register a BlackBerry smartphone with the wireless network
    Please wait for one "registration" message to arrive
    2) Reboot
    Pre-BB10 Devices ONLY. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
    BB10 Devices. Hold the top button down until the counter reaches zero. Wait for the device to be fully shut down (e.g., nothing at all displayed on the screen, no LED lights, etc.). Hold the top button until the red LED is lit. Wait through the full boot-up process. IF this fails, you can attempt the battery-pull method above, but it is normally NOT recommended unless nothing else works.
    See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
    Hopefully that will get things going again for you! If not, then you should contact your mobile service provider for formal support.
    Good luck!

  • A pop-up window advising of software update for Firefox appears and does not connect with server

    The window suggests strongly that I update software but when I attempt to update it does nothing but try to connect with server and never does

    * http://kb.mozillazine.org/Software_Update (Software Update not working properly)
    Remove the files in the updates and updates\0 folder.
    You may need to delete active-update.xml and updates.xml as well if present.<br />
    XP:
    C:\Documents and Settings\&lt;user&gt;\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox\updates
    (%USERPROFILE%\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox)
    If you have problems with updating then best is to download the full version and uninstall the currently installed version.
    You may need to remove the Firefox program folder to do a clean install of the new version.
    Do a clean (re-)install:
    Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
    * Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    * Do not remove personal data if you uninstall the current version.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • Error message "unable to connect with server. Check wifi connection"

    I started having the error message "unable to connect with server. Check wifi connection" when I attempt to use search function within a certain apps and when I try to download certain magazine (eg. National geographic).  I didn't have this problem with I first started using iPad, and no problems with connectivity when using other apps.  Can anyone help?

    You may not really be connected to your WiFi network.
    Your router may not have given your iPad a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
    Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPad (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
    If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc.

  • I cannot create a new business catalyst site with Dreamweaver CC 2014. The error message states that Dreamweaver cannot connect with server, try again later. How can I fix this problem?

    I cannot create a new Business Catalyst site with Dreamweaver CC 2014 (Mac). The error message states that Dreamweaver cannot connect with server, try again later. In addition, I am also unable to load remotely a previously created Business Catalyst site as it says there is something wrong with my username or password. However when I put my password in and press test connection, it says it has connected successfully. What is going wrong and how can I fix this problem?
    Thanks

  • TS3899 Have just uploaded iOS7 and now cannot get mail as device won't connect with server. Apple ID is ok  - any suggestions?

    Have just loaded iOS7 and now I cannot send or receive mail . Device message is : cannot open mail cannot connect with server. Any ideas?

    Had the same problem.  Deleted my account and readded it...still didn't work.  Had a call with Apple, and they couldn't figure out why the Exchange server wouldn't work.  They had me set up mail through Gmail, and that finally worked.  There must be a bug they need to fix for the Exchange Server. 

  • Client Not connected with Server

    Hi Experts
    I upgraded my Patch level from 9.0 PL8 to PL9.  Server and Clients are installed and it is working fine but one PC not connected with Server.  While I Connect SAP in landscape server selection Page Port Number shown as 40000 instead of 30000.   I changed Port No from 40000 to 30000 the error Message came as  [message 60070-99999987}.  I attached the Screen shot in this discussion.
    Please help me to resolve this issue.

    I have same problem and this is the solution
    Go to the directory C:\Program Files (x86)\SAP\SAP Business One\Conf
    Copy the file b1-current-user.xml and put it aside
    Go to the directory %USERPROFILE%\Local Settings\Application Data\SAP\SAP Business One
    Check the file b1-current-user.xml which is likely empty or wrong strings
    Rename the b1-current-user.xml file for backup
    Move the copied file into the directory.

  • No Finder Go "Connect To Server" option

    After installing OSX 10.6 I no longer have the Finder > Go > "Connect To Server" option. Command-K does not activate it. How can I connect to a known server? How can I get this option back on the menu?

    Thanks!!!!
    That helped me...
    I could pull up a list of other computers on the network (command-k), but when I tried to connect to any one, I got looped back to the list. Wouldn't connect at all.
    Deleting the finder prefs worked like a champ.
    rock on.

  • Replacement for Finder's "Connect to Server" interface?

    The Finder -> Go -> Connect to Server interface is a bit minimal, to put it mildly.
    Ideally, I'd like to be able to:
    • Rename the connections ("smb://192.168.1.32" isn't very helpful)
    • Organize them in folders
    • Sort by name, connection type, etc.
    • Specify whether or not to save user/pwd in the Keychain
    Anyone know of any third-party connection-manager utilities?

    That's what I was thinking. I have read numerous "how-to's" about this, and all of them say that this is possible, but I think what I am really reading is "How to copy files between computers" and not "How to use a PC as a server."
    Thanks again!
