[Q] Certain websites suddenly inaccessible on 4G - Samsung Galaxy S Blaze 4G

I'm stumped. Noticed my corporate (exchange) email had stopped syncing this morning, could not get it to start again. Assumed it was the usual refusal to sync that occurs periodically. Eventually established that if I am on WiFi, I can connect to the server, but cannot connect while on 4G. Verified this in the web browser as well and also when tethering my PC to the phone. Tried switching to google/open DNS from the Tmobile defaults but no effects.
I don't know where to go from here other than T-mobile tech support.

No internet using USB to PC

Apologies if this has already been asked/answered, but have spent the last two days looking for a solution..
When connected via USB I cannot establish an internet connection, unless I delete the T-Mobile proxy setting.
I've applied the regedit edit that's been mentioned as a solution, but this didn't work.
Is there anyway to use the pass through connection without having to delete the proxy everytime?
The main annoyance is that the phone won't sync with my exchange server whilst connected to the PC. I have mail set up to sync with exchange server and all other items syncing with my PC. My Hermes sync'ed with anything and everything.
Thanks
just leave the proxy out.
T-Mobile's proxy is a pain in the arse and causes all sorts of problems.
I deleted the proxy from my connection on t-mobile nearly three years ago and on every single device i have had since. never had a problem since.
If the proxy is there, it affects ALL internet connections, so when you plug it in to your PC, it is trying to go through a Proxy that you can only access over GPRS.
that's why proxies are a PITA and should be deleted permanently.
and no, it should not affect anyhting if you delete it. or not that i have noticed anyway.
Thanks will give it a go when I get home.
Seem to be able to access internet without the proxy, but forgot my usb cable so can't test pass though at work.. fingers crossed!
When I deleted the proxy I couldn't then send SMS texts...?
That's a completely random coincidence. The proxy has nothing to do with SMS whatsoever.
you can of course make sure that you are using GSM for SMS. start>settings>connections>advanced network>SMS
set it to GSM. if this is already set, then it has nothing to do with the proxy.
Says "Your text message cannot be sent" after I removed the proxy. SMS is set to GSM. Could it have altered any other relevant settings? Have put the proxy back now but it still refuses to send the message.
Any ideas?
no, wouldn't have changed anything else. The proxy has no bearing on SMS whatsoever.
Like i said, i reckon it is just a coincidence, otherwise turning the proxy back on would have fixed it.
If it is set to GSM already try the other three settings as well.
and a soft reset of course....
Have found a cable and tested - still no joy after deleting proxy.
Connecting to PC, and items syncing with host PC are fine. Mail syncing with Exchange server fails and can't access internet via pass through.
Browsing and syncing with the exchange server is fine when not connected to the PC.
Btw kempas - SMS works fine after deleting the proxy setting, as it should do.
Steve
on the handset:
start>settings>connections>wifi (NOT Wireless LAN)> network adapters
set the drop down box to Internet.
On the PC:
Open Activesync>File>Connection Settings
Set "This computer connects to" to the internet.
Dunno what it is in vista, i have avoided it like the plague....
I did a soft reset and tried again (a couple of time) with no luck, unable to send text message.
Went to settings, connections and run through the network provider setup wizard, let it reset the phone and tried again. Settings 'seemed' all the same but SMS now sent without issue.
Will try removing the proxy again later and testing with another SMS.
EDIT: removed the proxy and sent an SMS without issue this time... So was a "completely random coincidence" as rhedgehog said.
Still can't access You Tube via it's mobile client though, at least, it still says no videos...
All now appears to do what I expect after removing proxy and following rhedgehog's advice. Pass through now works Many thanks!
Also appeared that the t-mobile proxy blocks Windows live and messenger

Just Web N Walk I believe, not plus, so I guess messenger is a no no. Will bypassing their proxy end up with me being charged for data??

No, but it is against the t&cs to use IM software when on basic web n walk. Tmobile block the ports for IM software anyways, it seems for new customers since several old customers managed to get through.....i never could though, so the proxy would make no difference if it is on or off.
I personally am on wnw+ which is TOTALLY worth it for using the HSPA when out with my laptop on location.
Cheers for that. Won't really need messenger to be honest - but the proxy setting interfering with the pass through was annoying.

Log into My T-Mobile or call customer services and get the adult content filter turned off.
I think they blocked it to prevent kids blowing mummy and daddy's credit on watching videos.
Of course, Streaming is also against the T&C's of wnw standard, so it could be that this is why. I'm on wnw+ and had to turn off the filter to get it working.
Yep, that was it. Cheers for the reply...

FUZEinMYpants,
Are you using a large outfit like gmail or something like your company email? If the latter, does it only work on wifi when you are on your company's wifi network or Starbucks' wifis as well?
The reason I'm asking is that depending on the email servers (there are two, one for sending, the other for receiving mostly) you may only be able to interact with them if your coming from an IP address that falls within the range of whatever the administrator set. I for example could not send email when I went down to Florida because AT&T gave me a too different IP address than what I get in New York so I had to ssh into my email server and modify the range.
Your admin may only allow email to be relayed out and/or read if you're on the LAN which in this case, in your office or college on their wifi network connected to the local area network to which the mail servers are connected.
If that's not it then we may have a connectivity problem with your settings. Maybe a bad proxy configuration, your email server doesn't like wap.cingular which is behind a nat, maybe your email server requires a type of encryption you're either not specifying or is not supported by Pocket Outlook, maybe they're using imap and not pop and you're mixing that up, maybe they don't have encryption but they used funky ports for the vanilla protocols -- I'm going to stop typing until you tell me what the story is with your email setup.
In the meantime, to hold yourself over with the phone and without wifi, consider getting your mail through a webmail thing your server may run (I run roundcube) using Opera or PIE, depending on the webmail interface.

Check the setting in your email settings under advanced server settings and make sure that it says Netowrk conncetion media net or att isp. I have seen it default to Work and that locks it into Wifi. I send and recieve email everyday on EDGE since I do not have 3g within 40 miles of here.

Activesync mail not working over cellular connections (T-Mobile UK)

I have a touch pro 2 running a 6.5 ROM and I am having issues getting activesync (Exchange) mail working over cellular connections.
I have set it up, all seems OK. I can surf web pages, though it is slow - HSDPA does not seem to come up much. I am in London on T-Mobile with a flat rate data plan (Web-n-walk).
Activesync mail does not sync over cellular. If I manually initiate a send/receive, it often does nothing, sometimes pops up a notification to say that connecting to the internet access point (general.t-mobile.co.uk) failed.
If I enable wifi (just regular wifi, not wifi activesync) and connect to my DSL connection, it all works fine - so I am 99% sure it is an cellular issue or an issue with my phone provider.
Can anyone give me any advice, T-Mobile customer support is getting me nowhere.

Exchange sync

I have set up an exchange account on my touch HD. I cant quite work out how it syncs. Sometimes it seems to go across GPRS, but some times not, then needing my home WiFi.
Do some exchange servers require a certain bandwidth to work?
I still have not worked this out. Sync OK over wifi from home, but not HSDPA/3G.
Any ideas? Do specific ports need to be available from my data provider?

[Q] No "Push" email/messages going from wifi to data

N5 4.4.2. Straight Talk
It seems to be doing this the last couple of weeks. I get emails/hangout/email notifications fine on wifi, go to data, I can still use internet, but have to manually refresh email and hangouts to get new messages to appear. If I step back into wifi then everything starts working normally again.
Any ideas?

In general your phone will update the server again to it's new IP to PUSH to. When you are on WIFI you are on your network and attached to whatever IP your ISP leases you. When you are on 3G/LTE or whatever your phone is getting a leased IP address from the carrier so the server will need to connect to your phone different. Since the server only updates once the client connects it wont know till the "heartbeat" is sent again or you manually refresh.
By default the heartbeat slows down after some time if it hasn't gotten any new messages in a while. So it may start off at 30 seconds then slowly drops down to 10mins (think this depends on the server). Once a new message comes in, the server pings your phone and tells it to connect for a new message and then your phone downloads and starts over the heartbeat again.
When you change IP addresses by going from WIFI to LTE it should update the server but maybe there is a bug or something that it's not working correctly. I haven't tested this scenario on my device so i can't be sure but that's how it's supposed to work.
