Known issue: T-Mobile cellular access problems (iPhone Safari/Chrome)

Post by **Admin** » Sat Feb 21, 2026 10:23 am

We’re currently investigating an access issue affecting some users on T-Mobile cellular data, especially on iPhone Safari/Chrome, where ComputeX domains may fail to load or show DNS/security warnings.

Affected examples

Code: Select all
```
computex.cc
```
Code: Select all
```
www.computex.cc
```
Code: Select all
```
app.computex.cc
```
Code: Select all
```
forum.computex.cc
```

What we know

The ComputeX server is online.
DNS and TLS certificates are valid.
The site is reachable from other networks and test clients.
This appears to be a carrier/network path issue affecting domain access in certain mobile browser cases.

Temporary workarounds

Use Wi-Fi.
Use a different carrier/network.
Try a trusted DNS/VPN tunnel app such as Cloudflare WARP (possible fix/workaround for some users).

Note: WARP is a workaround and may not resolve the issue for everyone, but it can help bypass a problematic mobile network path.

We have already tested multiple server-side fixes and are preparing/escalating this with the carrier.

We’ll post updates as soon as we have more information.
