Hi there! I understand that after the recent site maintenance, your Tarassud+ app is no longer validating your credentials even though you are using the same ones that worked before. I’d like to help you get this fixed smoothly.

To start, could you please tell me:

- Are you getting any specific error message during credential validation?
- Have you tried resetting or re-entering your credentials?
- Is this happening for all users or just specific accounts?
- Have you noticed any other unusual behavior on the app or site since the maintenance?

Meanwhile, here’s a step-by-step plan we can try:

1. Clear Cache & Cookies: Sometimes old cached data can cause validation issues after updates. Since you’re on WebKit browser on Windows 10, clear your browser cache and cookies.

2. Re-enter Credentials: Carefully retype your username and password to ensure no typos.

3. Check Account Status: Verify if your account is active and not locked or suspended.

4. Check for Maintenance Announcements: Sometimes maintenance involves backend changes, like updates to credential storage or validation logic. Check if there are any announcements regarding changes affecting credentials.

5. Try Logging In from a Different Device/Browser: This helps isolate if the problem is device or browser-specific.

6. Network Check: Ensure you have a stable internet connection and that no firewall or security settings are blocking communication with Tarassud+ servers.

7. Advanced Check — Token or API Changes: If your app uses tokens or external API keys for validation, sometimes maintenance updates require regenerating these credentials or updating API endpoints.

Let me know what you have tried so far and any error details you see. This will help me guide you to the next best step.

If needed, I can also look into any ongoing issues related to credential validation post-maintenance for Tarassud+ and provide tailored support.
