Business Central 17 Web-Client access issue on Safari and iOS mobile app

(0) ShareShare
ReportReport
Posted on by 45

HI,

We have the issue on couple of different servers on accessing Dynamics Business Central web-client on Safari and iOS mobile/tablet apps.

Both are Business Central 17 (on-premise).
Both the servers are with Self-signed certificates and their web-clients are accessible on Chromes/Edge/IE. Although, these web-clients are not accessible on Safari or iOS mobile apps.

On checking the event viewer, there is some error message observed:
1. Microsoft.AspNetCore.SignalR.HubConnectionContext
Failed connection handshake.

Not sure if there is something missing on IIS or web-server settings.

Please assist. Some of our customers are using Business Central and have difficulties on using on iOS devices.

Scenarios:

1. Application is BC 17.0.16974.0

2. Currently Self Signed Certificate used and we have also tried letsencrypt for generating SSL certificate for web-site and its binding.

3. The web client access and BC app have no issues on Android.

Best Regards,
Manish Kutar

    Hello,

    2 things:

    For Android, check that your certificate also contains SubjectAlternativeName, like this:

    -SubjectAlternativeName MININT-B8BEF1K:8080/BC180

    Or you can get a new free certificate via https://letsencrypt.org/

    Especially for iOS, reinstall the app, it has been updated recently.

    Hi,

    Thank you for your inputs.

    Subject name and SAN are correct for the self-signed certificates. And iOS mobile app was installed recently within couple of day frame.

    I would try URL https://letsencrypt.org/ to check if this can help.

    Best Regards and Stay Safe,

    Manish Kutar
