Not sure what is going on here. Some months ago it worked and now it doesn't. I have a Windows 10 environment running a virtual machine for testing websites using Vagrant. The config in Vagrant is fine and sets up the IP address (192.168.33.10) as a private network. In the Windows Hosts file I have the development domain setup as well. For example:
192.168.33.10 test.dev
After 'vagrant up' all looks fine. A ping of both the IP and development domain works and a 'curl' of the development domain returns the correct html.
But when I put the development domain into a browser I immediately get an 'Unable to connect' error. The error comes instantly so it is getting to the server but then something is rejecting it.
Does anyone have any clues please?
After the best part of a week trying all sorts of things I found the answer. The domain '.dev' is now a legitimate global domain and Firefox and Chrome now force anything 'name.dev' to HTTPS which then throws back an error that it can't connect.

I've been without GitHub for 2 years now, and I'm getting sick of it.
In terms of web connection, I get a basic "This site can't be reached" - ERR_CONNECTION_REFUSED.
Attempting to use the desktop app results in more information

I'm running Win10 Home build 19044, connected to a private home network with no restrictions. What would be causing this?
Tried reconfiguring DNS, and it simply didn't change anything.
At the suggestion of FiddlingAway, I resynced my system time, to no effect.
For reference, I am living in the US, so there should be no issues connecting due to a countrywide ban. The web interface does not load, even on a VPN.
I've hit a brick wall and can't get past it as there isn't too much information out there on this problem. I have a VirtualBox on my Windows machine running Ubuntu with JetBrains Hub and Upsource installed on it. For making it public I am using apache2. I am able to run 'upsource.sh start' and start upsource ok, however when I try to access the website from an external network, the page gets stuck at 'Loading...' and then fails with '[name of my virtual box] server DNS address could not be found.'.
I am able to access the site from the internal network and everything works fine. I am forwarding a port from my public IP to the virtualbox port that is listening for JetBrains Upsource.
My hint is that the virtualbox is redirecting to itself and the client on the external network cannot reach that address. I am unfamiliar with apache so I'm not sure that it's configuration is setup properly. If anyone has run into this problem and fixed it or if anyone knows how to begin to debug/fix this... I'm all ears.
Thank you guys.
EDIT: The server seems to be hanging when the request for OAuth2 is made. Its making request to the virtualbox's local address rather than the public ip.
To anyone who runs into the problem in the future, I had to reinstall and put in the correct base-url. I'm guessing I was missing some properties that I needed to re configure and I could not find anywhere what all properties that I could configure.
I have a WCF service which is working perfect inside of my Parallels Bootcamp VM
However, I cannot get this working from outside, i.e. the MAC that parallels is running on
The IP address is shown as 10.211.55.3 using IP Config
The service is running via port 17377 so I am trying to use the URL 'http :// 10.211.55.3: 17377/CalculatorService.svc'
It appears as though this is normally caused by firewall issues
However, the firewall is off on both the windows VM and my MAC
Has anyone got any other ideas about what the problem could be?
I have tried this with another WCF service and still have the same problem, the 10.... IP address errors with invalid hostname
Paul
This has now been fixed thanks
If anyone else ever gets a similar issue to this the easiest thing is to change the parallels network to host only although this does disconnect the internet
I had to do that as well as modifyibg the host file on both the vm and mac to link the machines IP address to an specific host I gave it
Very new to the Self Host WebApi, but I am very impressed with its ease of use and extendability. At least through this tutorial. Everything I've done so far works on my development machine whether I use localhost, 127.0.0.1, or my LAN Ip (192.168.0.x) but I am baffled why I can't access the service from any other computer even others in the same subnet.
In short after going through the tutorial on the machine where it is running:
Browsing to
localhost:3636/api/products/
results in the expected xml return.
On another machine on the LAN browsing to:
192.168.0.x:3636/api/products/
results in a timeout
Data points for those who might know how this all interacts:
1.) My dev machine(192.168.0.x, server, host whatever you want to call it) has IIS on it; I was so paranoid it was in the way that I stopped it via the Administration GUI
2.) I have reserved the URL/Port with the following command line executions:
>netsh http add urlacl url=http://+:3636/ user=DOMAIN\USER listen=yes delegate=yes
>netsh http add urlacl url=http://192.168.0.x:3636/ user=DOMAIN\USER listen=yes delegate=yes
2.b) I've tried both of those together and individually, and tried changing the user to "everyone" to no avail
3.) I have tried to change the code in the tutorial to set the
config.HostNameComparisonMode = HostNameComparisonMode.Exact //default is Strong Wildcard
4.) I can successfully ping and tracert to 192.168.0.x from other machines on the LAN
5.) A friend recommended I setup a TCPListener and ensure I could telnet to that to eliminate the firewall as a possibility. If that logic is sound, the firewall isn't the problem
EDIT: Thanks for your help, here's another data point that I believe confirms it's not a firewall issue. I previously posted this connection when behind a rather obtuse (at least to a non Certified guy like me) Juniper Firewall/Router. I have since redone the tutorial on another machine (without IIS) on my home network and still cannot publish the service to other computers within my LAN. Any ideas?
Well it wasn't the hardware firewall, it was the windows firewall! yikes i wasted a bunch of time on that. Once I turned off the windows firewall (the code runs in an intranet anyway) everything worked.
Anyone know of a good site that explains how firewalls and wireshark interact; or i suppose that just has to be one's first test.
I would try a couple things:
First off, get rid of the HostNameComparisonMode line. That might actually disable requests coming from other machines.
If things still don't work, try getting rid of the URL ACLs and run your application as an administrator and see if that works. If that works, you may be able to add the URL ACL back on and not have to run as an administrator. You should only need the one with '+' as the hostname.
I faced the same problem when i tried to self host using OWIN. What worked for me was -
Run Visual Studio as an Admin
Remove any and all netsh urlacl port registrations that I had added while debugging this issue
Add a inbound rule to my windows firewall
I followed the instructions on this link
https://learn.microsoft.com/en-us/dotnet/framework/wcf/samples/firewall-instructions
Check out the section - To enable a port range in advance
That's it! I was able to call my api from other computers on the network.
Hope this helps...
I have a strange problem, I just installed my php web site on a shared hosting, all services were working fine. But after configuring my app I just could visit my web site only once, other attempts gives:
"The server is taking too long to respond.".
But from other IP i can access, but only once, it seems all ip addressess beeing blocked after first visit(even ftp and other services get down, no access at all from the IP), can anyone help to explore this problem ? I don't think that it's my app problem, the app works fine on my local PC.
Thanks.
First thing to try would be a traceroute to determine where your traffic is being blocked.
In a windows command prompt:
tracert www.yoursharedhostingserver.com
At the moment, trying to access this address gives this:
Fatal error: Class 'mainController'
not found in
/home/myicms/public_html/core/application/crApplication.class.php
on line 181
I have tried it multiple times and it didn't block me. It might be that You have already solved this problem.
As far as I know, the behavior described by You could only be explained by a badly configured intelligent firewall. It may have been misconfigured by Your host.
If You visit a site at a certain host and suddenly You cannot access an ftp on this host, then it's either a (really bad) firewall or a (very mean) site that explicitly adds a firewall rule to ignore that address.
Some things that You might look into:
It might be something with identd too. What was the service You have configured on Your host? Was it by any chance any kind of server-controll panel (that might have an ability to controll a firewall)?
Is the blockade permanent, or does it go off after 24h, or does it only go off after rebooting the server? Does restarting some services makes the blockade go off?
Did You install any software that "protects Your server from portscanning"? It might be a bit too aggressive.
I wish You good luck in finding a source of this problem!
Chances are that if you can access it once that its actually working. The problem is more than likely in the php code than in the server.
