Hello, 

I'm trying to get mobile application "ServiceDesk Plus v 5.9" work and having troubles.

Tested on devices: Samsung S10, Xiaomi MI9 (Android 10)

We have local login disabled and enabled SAML login via ADFS (Windows Server 2022)

I can login from my phone using Chrome, but when I trying to login via SAML using mobile application, getting the next error:

Certificates on ADFS are from our internal CA, I tried applying Let's encrypt certs - with the same result.
