Mattermost not Opening in my safari browser or any apple device

1

I have a self-hosted mattermost installation which works well on android, and pc but anytime it opens on the apple IOS devices, the page is blank. nothing loads

2

Is this with the Mattermost app, Safari, another browser, etc.?

Are you on port 8065 or 80, or are you using TLS on 443?

3

I’m using port 8065, and my TLS is on port 443. No, I’m not using the Mattermost app; I’m trying to access it through my browsers. I tried on a MacBook, but it didn’t work. I also tested it on my iPhone 15 using Safari and Chrome, and it didn’t work either. However, it works fine when I connect with the app

4

So, those two items are mutually contradictory. Are you going through a proxy of some sort to handle TLS? What is the SiteUrl in config.json?

In your browser, Command+Option+J should open the Javascript console. What do the logs say when you’re trying to connect?

5

My SiteUrl is set to the current URL I’m using for public access. I’m using Nginx Proxy Manager to handle my SSL configuration. I just realized that it works fine on my MacBook but not on iPhone browsers

6

I’m finally able to see this error

Safari acting up, huh? That’s a pain. First thing to try is a good old force-quit of Safari. Double-click the Home button (or swipe up from the bottom and pause if you have a Face ID phone) to see all your open apps, then swipe Safari up and away to close it completely. Sometimes that’s all it needs.
If that doesn’t do the trick, check your internet connection. Try opening a website in another app, like Mail or even just Google something. If nothing loads, you know it’s a Wi-Fi or cellular data issue. Toggle your Wi-Fi off and on again, or if you’re on cellular, try turning airplane mode on for a few seconds and then off again.
Still no luck? Time to check Safari’s settings. Go to Settings, then Safari. Try clearing your browsing data (History and Website Data). It’ll log you out of sites, but it can often fix weird issues. Also, sometimes a problem with the network settings can mess things up. In Settings, go to General, then Transfer or Reset iPhone, then Reset, and then Reset Network Settings. You’ll have to re-enter your Wi-Fi passwords, but it often helps.

if none of these solutions work, you can follow for more details instruction below.
