Cannot reach forum on iPhone and T-Mobile & Verizon cellular networks

[jamal]

I am not sure if this the right section of the forum, but here we go.

In the USA, while on the road, I cannot reach https://community.onsen.io over T-Mobile LTE celluar network either using Safari or Chrome mobile browsers.

1. When using an iPhone over T-Mobile LTE cellular network which I am mainly using, I cannot reach the website, however on any other wifi WIFI it loads fine.

I contacted T-Mobile tech support and they had the same issue. This is only site I am having issues with.

Safari browser:

Chrome browser:

On Chrome, the error is more descriptive:
The site can’t provide a secure connection
community.onsen.io send an invalid response
ERR_SSL_PROTOCOL_ERROR

2. A friend tried it On a iPhone using Verizon over WIFI using Chrome browser: and he got the following:

Note: I can reach https://onsen.io but not https://community.onsen.io on T-Mobile.

@jamal This is the first time we’ve heard that our Community can’t be accessed from the US. Can you please try again? Is the issue still there?

[jamal]

@khemry, yes this still an issue.
This issue is only iPhones as shown in the screenshots.

Here is video link showing the issue. BTW, I pasted https://community.onsen.io

So it only happens on iPhone? It’s okay on Android devices? That’s weird.

[jamal]

@khemry, yes it only happens on iPhones.

A friend of mine tried it on a Samsung Galaxy 8 and it showed up fine.

Could it be the SSL certificate that iPhone OS is sensitive to or an iPhone 11.x bug, currently on 11.1 ? Yes, it’s weird.
I’ll contact Apple tomorrow to see if they have an answer.

@khemry, I just contacted Apple tech support and they have the same issue even on A&T network.

I uploaded the iPhone log files so they can investigate further. I’ll let you know once I hear from them.

@jamal Thanks for the follow-up information. I hope you hear positive response from Apple. Good luck! :+1:

The error message ERR_SSL_PROTOCOL_ERROR error indicates that the browser is not able to initiate the secured communication at the moment. It’s almost impossible to pin it down to a single cause, it could be almost anything. There is no definite guide for managing this error. However, there are few changes or settings which help you to get rid you of this error.

• Configure Correct Date and Time
• Clear Browsing Data
• Clear Your SSL State
• Disable QUIC Protocol of Chrome
• Disable your Internet Browser Extensions
• Adjust Your Internet Security and Privacy Level
• Remove your system’s hosts file
• Check Your Antivirus Settings
• Check Your Firewall

It was an iOS bug. Apple fixed the issue starting with iOS 11.3.
