My big gray cylinder 5G Home internet has good signal and works reliably. But some percent of websites I visit simply refuse to load via the TMo 5g device, yet they work fine if I use my Verizon cellphone data, or a coaxial cable modem (which I have not canceled service on yet). I am guessing it's either a DNS issue between my Mac and the T-Mobile cylinder (eg: settings requiring technical help or updates), or a problem in the T-Mo network that is blocking some sites. After spending too many hours on the phone already with Tmo tech support for 5G Home, I am not excited about the prospect of engaging on the phone again. It takes too long, and the agents need more training and support. Has anyone experienced and solved this issue? Do you have technical insights? Is there actual written documentation somewhere that I could access? Thank you. (Honestly Tmo, you need to rethink your support infrastructure for 5G Home.)

More likely if its 5G just like the phone, it is not you, its Tmo. They're blocking UDP Access with 5G connections. Try a VPN and see if it works that way. I did that and the sites and access to voice programs like Discord and Skype worked fine after that. T- Mobile lies about their Data or does not give out proper information, Correct me if im wrong T Mobile ?

Thanks! I tried this on your advice. For anyone else reading this, let me save you some time. You can't disable IPv6 from the System Preferences control panel. You can only set it to local. So I did that, but I also googled and found this Terminal command to disable it: networksetup -setv6off Wi-FiAnd that does indeed show as "off" in the IPv6 panel of System Preferences, once you execute it. So thus set up, I tried again, and… no change. :-/ Some further data though: The site loads on my iPhone via Verizon cellular data, but NOT when the iPhone is attached via wifi to the Tmo 5g Home router. So does that point to the router, not the computer?

I just got the Gray cylinder and neither of the MacBooks I own would see the internet although they were connected to TMo wifi. I tried again but used a vpn and they worked like a charm. This made me very confident the issue was DNS. I changed the DNS settings in System Preferences/Networking to 8.8.8.8 and 8.8.4.4 and the MacBooks worked great even without using VPN. It was a very simple fix. What is beyond frustrating is I spent 90 minutes on the phone with TMo support trying to fix this problem and they were absolutely clueless. Actually, beyond clueless. All they would do is keep having me reset the device. I truly find it hard to believe they haven't resolved this issue for other Mac users and documented it for the support folks who have to deal with the public. C'mon T-Mobile, you're better than this.

I have the same issue reported above with various random websites not loading on my 5g iPhone. Yesterday, I went to get a covid test and my iPhone would not load the website to submit my insurance info…https://dcltesting-2.com This would not load on multiple browsers and I had no WiFi access. As soon as I connect to my work VPN, I was able to load this website perfectly fine. Good thing I had a VPN accessible. Any insight into why these websites are not loading? Is this a UDP issue as mentioned above? FYI. The website mentioned earlier in this tread does not load for me either via 5g on my iPhone…http://judiglova.com/

I had Duda Support help me and we disabled cookie tracking in the Privacy Settings of the current website I am developing. Now it is loading like normal for that site. Hope this helps people and T-Mobile Tech Support!

Well that might be true, Gov. website might Ipv4 but why is working from other providers? only issue is with T-Mobile !!! I have to say, I loved it and wanted to keep it but I have no control over which site is Ipv4 or IPv6. I just want to use it!!! so they should backwards compatible and fix it for all browsing, If One Site doesn't work. then what else not going to work???

T-mobile is IPv6 only. I am guessing that the government site is IPv4 only. Nothing T-Mobile can do to fix the issue. They are not going to add old IPv4 to there network.

I have done Trace Route from T-Mobile to “https://passportstatus.state.gov/” and it doesn’ Leave the router, last hop is the router but it resolved the DNS. if I do it from other internet connection, it travel through internet and different hop and it will get there. not with T-Mobile
I even went to the store to return my equipment, sales person tried it from his T-Mobile Phone or store WiFi and didn’t work either, but once tried it from other Internet providers, it worked without any issue. is amazing that T-Mobile hasn’t fix this issue.

What it turned out to be for us - T-Mobile is IPv6 only. Where my wife worked - they were IPv4 only. Can't believe some places are still IPv4 only since IPv6 has been around for over a decade. My wife no longer works for the company and we have gone back to T-mobile 5g internet and everything has been working well.
From this thread - it appears perhaps many places haven’t upgraded their technology in a timely fashion?

I also have the same problem with T-Mobiel 5G, Tried to access “https://passportstatus.state.gov/" and it wont load, but it load on other ISP, also noticed that it wont load on Tello or T-Mobile Cell service either. had the service for 24 hours and ran into this issue. had to call T-Mobile and cancel it because if one site doesn't work, what else doesn't work that I don't know?!! I was willing to keep it and was excited about the service and new service but unfortunately canceled it.

Update, it has been six days since I reset my home internet gateway, and again, I can no longer access my company's website or e-mail servers. I called tech support and they had me unplug the gateway for 5 minutes and restart it. After rebooting I can access my company's website. Not sure I want to deal with having to reboot the gateway weekly to get it to work.

I had this problem immediately upon activating my T-Mobile Home Internet Gateway, G4SE-1. I could not access my company's website or e-mail servers when connected to the Home Internet Gateway, but I could connect to the domain using a cell signal on my phone or when using a VPN on my computer. I tried restarting the router with no change. My T Life app does not have a reset button, so I used a sim removal tool to push the reset button on the back of the gateway for five seconds to reset it. After the reset, it updated firmware and I had to set it up again, but now it is allowing me to access my company's website. Very odd. I hope it doesn't happen again.

Same issue here. If I use my mobile hotspot, I am able to load anything. If I use my 5G home internet, I cannot load websites that I use for work. I am running through a VPN. Example website is datadashboard.fda.gov. My IT guy says it appears that it's any site that requires location. I can access these websites through my iPad but not my work laptop that is connected to the VPN. This makes me think it's got to be a setting on my laptop.
I can connect to same websites on other internets. Hotels are fine, even taco bell internet is fine so this make me think it's the internet.
I work from home and live remote so getting good internet speeds it HARD. I have great speeds with TM so I really do not want to switch again.

EDIT: I just reset my router via the T-mobile T Life app and now everything is working as it should.

Any head way on this topic? I have 2 laptops that have the exact same issue as has been described in this thread. I can use both normally on any other network, but T-Mo sites are not loading (see previous error). I can hotspot from my phone to T-Mo and then connect my laptop to my phone and all sites work…. Grrrr!

Working in Dell PC with Windows 11 pro, YouTube and Gmail work, other websites including T-Mobile.com will not load. Spent two hours on line with tech support. Progressively more technical. For the final solution is they don't know and call Dell. This computer is wired to T-Mobile box not using wifi. Wifi works on phone and tv. I find it funny that it won't load their own site. Kinda tells me it is incompetence and not malicious.
