Hi,
I have a .NET WPF C# application running on 4.7.2 framework .i had a working stable application for 6 years with users using by click once ,downloading the wpf application and some users using RDWeb .Suddenly from past 3 months all checks and validations regarding the application on click of a button are skipping ,but it works fine on my developer PC .So i am not able to replicate the errror .There was no change done to the code .(The only IT department change done was we had added Fortinet firewall 3 months ago(but i doubt this might cause an issue) .What should i do in this case?

1.Check firewall rules: Make sure the firewall does not block ports or protocols required by the WPF program.
2.Temporarily disable the firewall: Temporarily disable the firewall to see if the problem persists. If the problem disappears, it means that the firewall configuration needs to be adjusted (for example, add the application to the firewall's whitelist).
3.Logging: Check the logs of the firewall and WPF program to track the program running process and find out the specific reason why it was skipped.
4.Confirm whether the user program has been tampered with: Confirm whether the user program has been tampered with (you could consider decompiling) and confirm whether SQL injection occurs.
