HTTP proxy server connection error

My iPhone4S can't connect well to 3G, only works properly with WIFI connection. When i try to navegate with safari or other apps, HTTP proxy error is shown. I only receive notifications, but when i try to open the specify app: server error. Its weird, because for instance, whatsapp and mail clients like sparrow works properly with 3G. I can update my mail and send whatsapp, but i cant receive or send any attachments.
I've tried to reset my iphone, and reset my network configuration, but the problem is still there.
Thanks everyone!

I had this problem. It started when I took my unlocked iPhone from Australia on a Telstra SIM to the U.S. and put in a Straight Talk SIM. I used unlockit.co.nz to generate a new APN for my phone while on Straight Talk, which worked fine.
However, upon coming back to Australia and reinserting my Telstra SIM, I couldn't access HTTP. My VPN would start over 3G and I could get push notifications and data in some apps, but anything that used HTTP, including Safari, would give me the proxy error or a network timeout error. Wifi worked perfectly.
I called Telstra and they said it wasn't them. I was sitting on hold with Apple Care when I thought to try inserting my colleague's Telstra SIM into my phone and, voila, it worked perfectly. I hung up and called Telstra back to complain but while on hold I put my own old Telstra SIM back in only to find that I had fixed my problem.
So try inserting a known, working SIM from the same carrier and see if that fixes your problem. Stopping into one of their stores may be the answer if you don't have any other SIMs handy.
I suspect that somewhere in the iPhone an HTTP proxy for 3G setting was set and stuck, and trying a new SIM erased that setting.

Http proxy server connetion error

i have built a proxy server between iis and client

error produeced is : Server not found - UnknowException java.net

thanks in advance

Here is a java HTTP server you can use instead of IIS (comes from the burrowing through firewalls article). This class allways sends the same response to any request on port 80 but it should be a good tool to test your proxy server (as to what requests the proxy sends and if the proxy pickes up the response).
Stop IIS on the IIS pc and run the following class:

Outlook is unable to connect to the proxy server.(Error Code 10)

Hi,
I had problems with RPC proxy, I was trying to setup cutover migration.

But after this change my outlook was not working anymore
The settings before the change were:
Name Server CertPrincipalName TTL

So I set this back to the original (above) but this didn't helped...
Outlook 2013 and Exchange 2013
There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site mail.abc-company.com.

Hi,
Please make sure the mail.abc-company.com is included in your Exchange certificate which has been assigned with IIS service.
If possible, please run the following command for double check:
Get-ExchangeCertificate | FL
For Autodiscover service, please run

Outlook is unable to connect to the proxy server. (Error code 0)

Hello,
I have just commenced a Exchange 2007 SP3 to Exchange 2013 SP1 migration following the following guide: http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration.aspx
As per the above guide, my 2007 environment is now known as legacy.company.com and my 2013, webmail.company.com.
I'm using the same certificate on both boxes and it has the names autodiscover.company.com, webmail.company.com and legacy.company.com. All that seems to be working fine.
OWA is functioning perfectly, hitting https://webmail.company.com will pass the user off to https://legacy.company.com if the mailbox is on 2007. Alongside this, Outlook also has no issues connecting to 2007 mailboxes with the client proxy settings
being reconfigured to https://legacy.company.com automatically.
My problem comes when a mailbox is migrated to 2013. OWA functions fine and presents the mailbox but Outlook is unable to connect, presenting the error:
There is a problem with the proxy server's security certificate.
The name on the security certificate is invalid or does not match the name of the target site webmail.company.com.
Outlook is unable to connect to the proxy server. (Error Code 0)
If I modify the Outlook client's settings and disable "Only connect to proxy servers that have this principal name in their certificate: msstd:webmail.company.com", Outlook connects and functions fine.
I'm at a loss and have tried everything I can think and find on google. Any suggestions would be greatly appreciated.

Hi,
Please refer to the following article :
http://support.microsoft.com/kb/923575
Cause:
This issue may occur if one or more of the following conditions are true:
The connection to the server requires a certification authority (CA).
You have not trusted the certification authority at the root.
The certificate may be invalid or revoked.
The certificate does not match the name of the site.
A third-party add-in is preventing access.
Solution:
To examine the certificate, follow these steps:
In Microsoft Internet Explorer, connect to the RPC server or to the secure server. For example, type
https://www.<var>server_name</var>.com/rpc in the Address bar of the Web browser, and then press ENTER.
Note The <var>server_name</var> placeholder references the RPC server name or the secure server name.
Double-click the padlock icon that is located in the lower-right corner of the Web browser.
Click the Details tab.
Note the information in the following fields:
Valid to
The Valid to field indicates the date until which the certificate is valid.
Subject
The data in the Subject field should match the site name.
Hope this helps!
Thanks.

Will someone please help me set-up Acrobat to send a PDF via webmail? Acrobat returns a message "Server Connection Error .... Port 143 unavailable"

Are you using a Microsoft or Apache web server? If so, you can submit to a server-side script, which will bypass web mail and client-side email software such as OUTLOOK.

Server Connection Error 403 - HP Photosmart 6520

My scanner all of a sudden stopped working and I got "Server Connection Error 403"
How do I fix this?

Hello @SeanTK ,
Welcome to the HP forums.
I understand that you are getting a Server Connection Error 403.
I would like to help.
You would only receive the 403 error if you are using scan to email.
There are a few things you can try to resolve this issue.
Hard reset the printer.
While the printer is turned on, unplug the power cord.
Wait at least 30 seconds.
Plug the power back into the printer.
Test the scan to email.
If you still get the error, try setting a manual DNS.
The following post by happytohelp01 has instructions for setting the manual DNS.
It is for a Photosmart 7510, but the steps should be very similar.
Re: Efax 7510 still won't work after turning off/on ePrint
If the Error is still present after setting the manual DNS, you should cycle your network.
Turn off your network devices, including the printer.
Unplug the power to your router for about a minute.
Plug the power back into the router.
Turn on your printer, and the other network devices.
When the blue wireless light on the printer stops blinking, try the scan to email.
Another option is to remove then re-enable the printers Web Services.
This will act like an uninstall and reinstall.
Caution: removing the printers Web Services will cause it to permanently loose its ePrint address.
If the ePrint address has been customised then that address will be lost forever.
Once you enable the Web Services again you will have to setup the scan to email.
This will provide you with a new pin.
If you need further deatail on any of the steps, please let me know.
You can also call our Cloud Services at 855-785-2777.

Download Server Connection Error

I tried updating my desktop skype because it was being cruddy, but the updates wouldn't go through because of a "download server connection error." My friend suggested that I delete my old skype and reinstall it, but when I tried to do so, the same message popped up and offered a link to a supposed "solution." But when I clicked on it, it simply sent me back to the original page in a never ending loop of downloading failures. I looked up what to do, and it seems I'm not the only one with this problem. Others seemed to been having success when sent this link http://download.skype.com/msi/SkypeSetup_7.4.0.102.msi however, went to check it out, the page was deleted so I had no options. So now I'm stuck, and unable to download any program due to this error, which I have no idea what it is or how it's caused. If I could have some assistance ASAP, that would be great! I want my desktop skype back so I can share screens and see my friend while using my desktop. Thank you for your time, Chrissy.

On my computer and Internet connection it says it will download the file in 18 seconds but it downloads it in about 8 seconds. I downloaded 3 copies in less than 30 seconds all over wireless. If you are having issues downloading it you probably have a slow or intermittent Internet connection. If you are going wireless try to move closer to your wireless router or go wired.

Server Connect Error HP Photosmart

I just bought an HP Photosmart 5512
Im trying to set up the eprint and I keep getting a server connection error that says to check the connection or enter my proxy address.
I've tried several solutions and nothing seems to work. Help

hi jessyb03, welcome to the forum and sorry to learn that you are having this issue.
Hope you are doing great otherwise thought
Without having an understanding of the configuration that you are using is virtually impossible you me or anybody else in the forum to properly assist you, I will suggest for you to read this Post and then please include as much information as possible to make it possible for others to actually have a change to formulate a theory and provide you with suggestions.
There are some general steps that I can recommend to you in the mean time for you to try;
Make sure that all this is in done.
- Set an static IP Address for your printer, You will have to do your research to see what is the procedure to accomplish this is your OS, Router and other peripheral in this case most probably your printer.
- Use Google public DNS Servers 8.8.8.8 and alternate 8.8.4.4 (the reason that I recommend this is because I have use them all the time and have not seem conflict of any kind)
- Make sure that your printer have the most current firmware and software available for them (remember most of the updates in firmware and software are to FIX ISSUES and sometimes are to add functionality)
- Make sure that your Operating system is updated (To a lesser extend this are also updated to FIX ISSUES although some times can create them as well, mostly they are update to patch security issues) it may be important.
- Check if you can accomplish what you are trying to do with all security applications disable sometimes this applications will see and legit process as a thread and treat it as, if you find that this is the case you most to the research that to be able to allow the process being block to work with the current security applications you use.
- If you are uninstalling some application try to do it in safe mode, In safe mode you OS will load basic and mostly critical drivers the same with applications that start with your operating system this way it may be easier to uninstall any software, application, utility or driver that you are trying to remove. This step is only needed if you are uninstalling something.
The steps aforementioned will help establish that is not any of this circumstances creating the issue you are experiencing and is a more isolated issue. And if this is the case please post again with all relevant information please I reiterate this will give all visitor of the forum a good chance of the to understand and provide suggestions to you.
Hope this helps;

I want some other way of connecting to Proxy Server Irrespective of Httpclient and setting system properties and then making url Connection ,these ways are clear to me .
I found one API HTTPClient (not belonging to apache Httpclient) its different
u check this at
http://www.innovation.ch/java/HTTPClient/api/index-all.html#_S_
But the problem is this API Does't support NTLM
i tried to found higher version of this API but i did't get .
API should support :
1. NTML
2.JDK 1.4
3.SOCKS (not necessary)
4.HTTP protocol (other like FTP ... not necessary)

HTTP proxy server connection error
