I was using SonicWall Global VPN for a long time and it was working perfectly. But I am having trouble in connecting it for last few days. I have tried the following, but nothing helped.
Uninstalled Hamachi VPN
Uninstalled and re-installed SonicWall
Turned-off firewall.
Turned off anti-viruses
But it is working fine in my friend's machine, it is working fine.
Not sure what is the problem with my machine.
Can anyone suggest any ideas ?
Sometimes sonic VPN is not working because ISAKMP packet sent option is not enable. We need to mark it restrict first packets.
steps:
1. Go to File menu
2. Select properties
3. Click to Restrict the size of the first ISAKMP packet sent.
What error are you getting while connecting ? If it's stuck in connecting , it would be the OS version and GVC versions are not compatible !
Windows 7 : GVC version 4.7
Windows 8 and above : 4.9.9

I've downloaded the latest arm package from Pritunl website: https://client.pritunl.com/#install . Then, I imported an ovpn profile that worked perfectly well on my older (intel) mac and on my coworkers laptop. But, the vpn keeps getting set to disconnected whenver I hit the connect button. In system logs, I see - failed to sync config. In server logs - Unexpected profile exit. I've tried downloading the client again and reimporting the profile but none of that's worked so far.
Current Pritunl client version - 1.2.3128
Had the same problem on my m1 Mac. We solved it by restarting the pritunl service at the server side. After doing so, problem disappeared.
Good luck.
TCP connections work fine as I am able to converse with someone over zoom and teamviewer. However, whenever I attempt to access another webpage, I get a network error. Google seems to work fine for some reason but any webpage I go to listed by Google fails to connect. The only way I can open up my http connections is by ending a task called "init" inside of task manager. This shuts down my vscode as well as my ubuntu terminals I have running. If someone knows the solution please do tell. It's really annoying having to close out my vscode and terminals as well as my local servers to look up information and debug.
I found a fix to this issue.
So I was running a Windows Subsystem for Linux and my Windows Build was outdated as well as WSL. When I updated Windows and upgraded to WSL2, my issue was resolved and I don't seem to get any more network errors.
I want to use terminal/console of ubuntu 14 installed on virtual machine running on cloudstack 4.6. I am able to use ubuntu 14 desktop normally but whenever I try to use the terminal from it, i get "Client communication error please retry later". Following is the screen shot of the error.

I am using college network behind a proxy server, could that be a problem ?
any suggestions ? Does anybody know where I am going wrong ?
Quickest way to troubleshoot this - on the browser window that houses the broken terminal, do a view source. In there you'll find a URL direct to your console proxy server. Copy and paste that URL into a new window and see if you can hit it directly. I'm guessing a firewall issue...
When I try to start debugging my windows phone 8 app in Emulator WVGA 512MB the following error message is showing
The Windows Phone Emulator wasn't able to connect to the Windows Phone operating system:
The emulator couldn't determine the host IP address, which is used to communicate with the guest virtual machine.
Some functionality may be disabled.
and the emulator is always showing The Windows Phone OS is starting...
Can't understand what's the problem. Please advice.
This worked for me (found here):
follow the following steps to solve this problem
1.go to network and sharing center
2.go to change adapter setting
3.go to v Ethernet (internal Ethernet port windows phone emulator internal switch)
4.right click it and enable it(if already enabled then disable and enable it again).
At last the problem is solved.
Open Hyper V Manager
Delete all installed Virtual Machines
Delete all Virtual Switches
Restart system
Rerun visual studio

I had the same problem. After a long investigation and checking the event log, learned that windows firewall is blocking the emulator connecting to the virtual machine. With that information it is simple to fix the problem.
Yes! Just navigate to Control Panel -> System and Security -> Windows Firewall -> Allow app or feature through Windows Firewall. And click on Add another app button and browse the emulator's path (typically "C:\Program Files (x86)\Microsoft XDE\8.0\XDE.exe" but may vary based on your installation location). Choose the appropriate network type that you want and add the new item.
Now go back to VS and run your application (close any emulator instance that you have opened already), everything should work fine now!
the solution that worked for me :
open Hyper V
Select ur VM and go to Virtual Switch Manager.
Select Windows Phone Emulator Internal
if your connection is Internal then , check the Enable VLAN Identification option
press F5 from VS .
good luck!
Just reboot
No magic needed. Just reboot your development machine after installing Windows Phone SDK.
what your describing is usually due to a Firewall of a third party Anti-virus.
If your using Symantec follow this procedure https://stackoverflow.com/a/26326528/4446346
If your using Windows Firewall follow this procedure https://stackoverflow.com/a/27685167/4446346
and If you'r using AVG do the following procedure:
open AVG and go to-->Options-->Firewall Settings-->Expert mode-->Advanced Settings.
Check the "Allow any traffic from/to virtual machines supported by firewall"
and click "OK".
One more thing you must do is go to the "Windows Phone Emulator Internal Switch" and uncheck "AVG network filter driver"
open Network and Sharing Center-->Change Adapter Settings-->Properties
Uncheck "AVG network filter driver"
If you are loading the emulator for the first time, it behaves just like the phone (on first boot) where it will install the initial set of apps and configure them. Which is why the first start will take a long time. You can actually open Hyper-V manager and connect to the VM you had selected at the time of initiating debug - to see the actual progress of what is happening.
Hope this helps.
You can disable Hyper-V from Program and Features and reboot your machine twice. Everything will be default. Enable Hyper-V and reboot twice and everything should be working again.
Also you can check if your vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch) in Network and Sharing Center is enabled (mine was not, and I got same error like you).
Check that you have enough free space in your hard drive.
If you have a computer with a touch-screen and get this error, it can be because Hyper-V is trying to port over the touchscreen-fx to the virtual device.
This is (when found) easily corrected:
Shut down all attempt at launching virtual devices.
Go to: Hyper-V Manager->Hyper-V-settings->Physical GPU:s // Uncheck box "use this GPU with RemoteFX"
Try uninstalling vmware player 12 if you have ,I have tried several ways but nothing works until I remove it.
Hope it could help you.
When I yesterday returned to Visual Web Developer I was no longer able to run/debug my projects. Clicking the green play button launches ASP.NET Development Server (and it shows up in the systray) but the browser only shows the error message "Firefox is not able to connect to localhost:58127" (translated from Swedish). IE7 says "Cannot show web page".
I cannot figure out why this happens. It worked a couple of weeks back. Could there be a Windows setting that mess things up? (I've tried to disable the firewall without any change.)
Are you using Vista? I've had the same issues with recent Vista updates.
Firstly, make sure Visual Studio is running "As Administrator".
Secondly, when the browser launches, replace "http://localhost:" with "http://127.0.0.1:". If that works, then its because a Windows Update messed up your hosts file.
If this is the case, make sure you hosts file has this line in it, uncommented: "127.0.0.1 localhost"
my hosts file is in this directory: "C:\Windows\System32\drivers\etc"
yours will be something similar to that.
Are you perhaps using NOD32 or any other antivirus that may cause problems?
I encountered this issue today and just wanted to elaborate because my hosts file had "127.0.0.1 localhost" already defined.
I was able to see the default IIS site by referencing localhost but when I tried debugging in my IDE it would always display "cannot display webpage" in IE and "Oops! Google Chrome cannot connect to localhost" in Chrome.
I opened a command prompt and typed "netstat -a" and reviewed the results. I saw that my port used by my debugging web server was listed as "LISTENING" on the local address of [::1] only:
TCP [::1]:64212 [ComputerName]:0 LISTENING
What's unusual to me is that debugging worked for a period of time and then it seemed like all of a sudden it stopped. The first couple times it happened I re-installed Visual Web Developer Express 2010. This became rather annoying because it was a long process and the problem continued to resurface after what seemed to be an arbitrary period of time.
This latest time I changed my hosts file to include "::1 localhost" (the opposite of this solution and numerous others I found online) and that has resolved my issues with my debugging environment.
I'm grateful this resolved my issue but am still curious as to why and how my debugging environment seems to change. Additionally, I'm curious why there are multiple loopback addresses other than 127.0.0.1. Is "::1" an ip6 standard? If so, shouldn't localhost be routing to 127.0.0.1 and interpreted by the tcp/ip stack as the same as ::1?
I had this problem with Visual Studio 2013. I have set the Firewall system manually. This means that, at the time of communication by programs Firewall notify me. Incorrectly linked to "devenv.exe" was blocked by the Firewall. Correct mode of communication "devenv.exe" will solve the problem. in your case cheeck Firewall options and filtered communications.
