iOS 12.2 Problem

Ralf

Hi,

today I checked Mango 3.5.6 with Safari and Chrome on iOS 12.2.
It doesn't work correct, only the charts working, animated point-values in SVGs and dashboards are showing nothing...

No problems with any browser on mac, windows or linux OS.

Any solutions for this bug?

with any browser on

Hi Ralf

If things are not working there will definitely be errors in your browser's console and/or in your ma.log file that can point us to what is going wrong. Please review this document: https://help.infiniteautomation.com/reporting-bugs

Without screenshots, logs and errors, no one can really help...

Hi CraigWeb,

that's right, sorry...

ma.log:

Is your server by any chance behind a reverse proxy or firewall? Something is blocking web socket connections which is what the <ma-point-value> and other components use to show the live value.

Ralf

No, everything necessary open.
The strange thing is, that with windows or mac or android OS there is all ok, the svg and the ma-point-values are showing the live values.
With iOS 12.2 only the charts are working...

CraigWeb

Will have to wait and see what Jared says, if you could give any more information it would only help.

Screen-shots from your iPad?
Did this stop working after an upgrade?
Did it ever work?
Is it only on custom dashboards?
Do the standard dashboards such as watchlists work properly?

Ralf

Hi CraigWeb,

thank you, my answers:

Did this stop working after an upgrade? -> No upgrade.
Did it ever work? -> this is the first time I check Mango with an iPad.
Do the standard dashboards such as watchlists work properly? -> No, no values and timestamps, only Device Name and Name are visible.

Here are the screen-shots:

Are you connecting to Mango over the internet? Do you have HTTPS enabled? We see this most commonly when there is an ISP transparent proxy which doesn't handle WebSockets correctly.

Ralf

Hi Jared,

yes, I connect to Mango over the internet and https is enabled.
I don't understand why this bug only exist with iOS. If the reason is Websocket or ISP, why it works with Android, WIN and Mac?

CraigWeb

I have not had this problem before on an Ipad, don't really have one to test ATM but you could maybe do some troubleshooting like putting your pad on a WiFi with a different ISP or hotspot from a different mobile provider.
BTW this probably won't be your last frustration when it comes to IOS and browsers.

iOS / Safari don't exactly have a great track record when it comes to web standards.

Unfortunately this does seem to be a bug in Safari, see here - https://stackoverflow.com/questions/37898048/websocket-network-error-osstatus-error-9807-invalid-certificate-chain

Since the message there says "Invalid certificate chain" it might be worth checking your certificate using a site like https://www.ssllabs.com/ssltest/

PS I would recommend you to try a different browser but I don't think it will make any difference as Apple in its infinite wisdom prohibits using anything than its own Safari browser engine on iOS, so Chrome on on iOS is a basically a skinned version of Safari.
