Support Request: Bad Request error

Description

Version 9.9.11396 Build 7305

On website https://pz.gov.pl/pz/index I click "Zarejestruj się" button which should take me to https://pz.gov.pl/pz/registerMainPage but instead I get a "Bad Request" error.
This problem only occurs with a SiteKiosk Registered User account and so far I've had no problems opening that page.
All other pages works fine.
The same thing happens when I use a different network without a proxy.

Hello,

The behavior is reproducible and appears to be caused by an incompatibility between the website and the Chromium CEF engine used in SiteKiosk Classic, which results in a "Bad Request" response from the server. The error page itself also seems to be generated by the web server rather than by SiteKiosk.
However, this issue does not appear to be related to the specific CEF version, as the same behavior occurs with the previous SiteKiosk Classic version 9.9.7077 but more because of changes to the website code, especially as it has been working fine so far.

As only workaround within SiteKiosk Classic, I found that switching to the legacy Internet Explorer engine (Start Page & Browser > Metro IE Skin or, in your case, you can then select the Start screen skin under ‘Internet Explorer’) allows the page to load correctly. Please note that this will cause compatibility issues with other websites, so this solution is only viable if you are exclusively using the affected pages.

Otherwise, the issue will need to be further investigated by the website’s developer.
You can find additional information on debugging websites in SiteKiosk Classic here:

Alternatively, I would recommend considering switching to our current product, SiteKiosk Online, where this website works without any issues. SiteKiosk Online offers centralized server-based configuration, flexible content management, and full server-side license administration. https://www.sitekiosk.com/en/sitekiosk/
