Troubleshooting (Anyconnect, cross-platform)

So far Anyconnect has caused few problems. But if something does not work as intended please send an email to vpn@hrz.uni-marburg.de. Until the problem is solved, using the supplementary WebVPN-Service has proved to be a useful workaround. You can find it documented on http://www.uni-marburg.de/hrz/internet/vpn/webvpn. If so far you have used VPN to send mail via the SMPT-Server the Philips University provides, reset your mail-client to SMTP-Auth, see also: http://www.uni-marburg.de/hrz/internet/mail/config.

Individual websites/journals/databases not accessible

If you can't access a certain website, but your VPN-Client is connected and most access restricted sites show up just fine, please try the following first:

  1. Close your WWW browser, if necessary restart your PC.
  2. Start the VPN-Client and establish the connection
  3. Start the WWW browser
  4. Now clear your browser's cache like this:
    Firefox: Tools menu -> Clear Recent History... -> From the Time range to clear: drop-down menu, select the desired range; to clear your entire cache, select Everything
    Click the down arrow next to "Details" to choose what history elements to clear (e.g., check Cookies to clear cookies) -> Click Clear Now
    Internet Explorer (Windows): Safety menu (in the upper right) -> click Delete Browsing History... -> Deselect Preserve Favorites website data, and select Temporary Internet files, Cookies, and History -> Click Delete
  5. Try to access the page again 
  6. If you still can't get access, please let us know. When doing so always state the exact URL or Link of the resource you were trying to access.

The measure described above often already leads to a solution. Even so employing the WebVPN can again be a workable solution.

Automatic update fails


Newer versions of Anyconnect come with automatic updates, that is Anyconnect normally downloads and installs the most up-to-date version of itself upon establishing a connection. This should happen without the need for user intervention. The VPN connection reestablishes immediately afterwards on its own. If this process fails, deinstall the current version of your VPN client and then reinstall

Access to publishers' websites works well, but CMS is not accessible

Presumably you have run into an address conflict. If you are using a NAT Router (as is now the case with most DSL and TV cable internet connections), it will often provide internal IP addresses like 192.168.x.y with x ≥ 1 to its clients. Since those addresses (except x=0)  are used used in the UMRnet, you will encounter an address conflict. If at all possible, configure your router to provide addresses of the kind 192.168.0.y.
