I'm using CLLocationManager to determine the current location and i'm using maps.google.com for reverse geocoding. Whenever I switch from wifi to 3g network and try to run my app which gets the current location, the map application launches with a message 'could not connect to the internet' even though i have a good 3g signal.
This happens everytime. Anyone seen this type of behavior before ? Any ways to work around it besides preventing the app in the background? I am releasing the locationmgr object so there is no cache.

The OPTION/POST Request is failing inconsistently with a console Error as err_timed_out. We get the issue inconsistently, it's only observed sometimes. Otherwise the request gets proper response from the back end. When it's timing out, the request doesn't even reach the server.
I have done some research on the stuff and found that due to maximum 6 connections to a resource restrictions it may wait for getting a connection released. But, I don't see any other requests pending ,all the other requests were completed.
In the timeline I can always see that it stalled for 20.00 seconds. Most of the time the time is same. But, it only shows that its been stalled for some time nothing else in the timeline.
The status of the request shows failed ERR_Connection_Timed_Out. Please help.

I've seen this issue when I use an authenticated proxy server and usually a refresh of the page fixes it.
Are you using an authenticated proxy server where you are seeing this behavior? Have you tried on a pc with direct access (i.e. without proxy) to the Internet?
I've got the same problem when I choose another ISP. I thought I would have only to put my new ID and password, but it wasn't the case.
I have an ADSL modem with a dry loop.
All others services were fine (DNS resolution, IP telephony, FTP, etc).
I did a lot of tests (disable firewall, try some others navigator, try under Linux, modem default factory, etc) none of those tests were successful.
To resolve the problem ERR_TIMED_OUT, I had to adjust the MTU and MRU values. I put 1458 rather than 1492, which is the default value.
It works for me. Maybe some ISPs use different values. Good luck.
I am calling a third party web service from app engine. This particular service is picky. I ran into an issue where calls would work fine for a while, then stop working, then start working again. I realized that if I manually stopped all instances in the admin console, that the calls would work again.
I setup a proxy to route the calls through that so I could see the headers and all detail. I think I have tracked the issue down to the following. After an instance has been up for a while (the app usually just needs 1 to 3 instances right now) app engine will start using the IP address of the destination as the value for the host header instead of the hostname. Well the service doesn't like that. Whether it should care is another matter.
So my question is, why does app engine use the ip address for the host header eventually instead of the hostname? And, of course, is there anything I can do about it? I know that I cannot set the host header, but maybe there is something else that can be done.
Thanks for any insight.
First, thank you for finding this behavior. We have had intermittent issues with urlfetch for a long time, and will try to detect if this is the issue.
One thing you could try is to target a specific instance/module:
http://instance.version.module.app-id.appspot.com
and cycle through the instances. If you just target the module, it will kill the instance after some inactivity. So, perhaps that would not trigger the GAE DNS shortcut.
Another trick would be to add a fake, random, query string after your url: ?foo=D7hfka67h. Perhaps that would prevent GAE from recognizing the repeat url, and trying to shortcut the DNS.
i have done a security app which locate a iPhone and send the GPS location of the phone through message to an associated number this functions works good until iOS 5, but the issue is sending SMS without users knowledge is restricted in iOS 6, so i need a help here instead of sending message, is there any other possible way or replacement for this function? any answer related to this method are appreciated.
Thank you.
You haven't specified whether your ios app has a server. If yes, you can transmit location to server and that in turn can transmit it to intended user via specific api.
If this is not correct, APNS is your friend. This is a way to send messages to desired devices only, the ones who explicitly registers through your app.
Another quite equivalent option is to store it in public back-end like parse.com. As soon as other devices start your app, they can pull your location from there. If their device is already live, parse.com can make sure to notify them as soon as you change your location value in their DB.
I have written a simple web Application which is running(on Tomcat Server) fine on my local system.But when I tried to access from a different system using http:/my_ip_address:8080/Projec1/My_Application. Its showing this error
Network Error (tcp_error)
A communication error occurred: ""
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
I know many of you must be well versed with this kinda error.But for me its kinda new.I would be happy if you state possible reason and solutions(Please tell me if there is configuration is required in Server step wise)
Thanks All
I forgot tell you all that i found the answer of above question, actually there was proxy setting problem.This is what i did
Open internet option in IE.
Goto LAN setting in Connection option.
In LAN Setting there is advance setting tab, click it.
You will see a Exception box at the bottom.
Type the IP Address form which you want access.
eg. 10.200;*.xyz.com
This setting is to be done on system from where you want to access your web application.
Starting IP address where application is running 10.200.---.--- that is why in exception box it is mentioned as 10.200;*.(your Interanet Server Name)
Hope this will help.
Thanks
I am trying to access same python web app in GAE from firefox and IE with different user login and when I start the IE session I get the following error with IE going standstill.
why?
error: (10054, 'Connection reset by peer')
I presume this is on the dev_appserver? Bear in mind that the dev_appserver is single-threaded, so it will not handle multiple concurrent users well.
Can you give more detail about exactly what sequence of operations causes this? Are there any stack traces on the dev_appserver console when it happens?
Do you get a similar outcome when you start the IE session first, then the Firefox session? what about trying two IE sessions, two Firefox sessions, that why you can rule in/out browser differences.
Eclipse creates multiple instances on range of ports and few of them conflicts with pythons working. I could not locate the exact port or did not know how to stop eclipse from doing so. I did simple netstat and observed this behavior of port capturing and causing reset
