Hello Ayoub 2li,

Thank you for posting on the Microsoft Community Forum.

Will devices within your domain encounter problems accessing other websites? Maybe the website has blocked the workstation devices.

Check the website's configuration files, permissions, and routing to ensure they are correctly set up and compatible with the server.

Check the firewall and other network policy settings on the server. Ensure that there are no rules set to prevent access to these websites.

Security permissions: Check the security permission settings of relevant websites on the server. Ensure that users have sufficient permissions to access these websites.

Grant the appropriate permissions to the correct users or groups to resolve access issues.

You can try to export GPO settings on one problematic machine and check if there is related group policy setting in the domain to block this website.

For checking Computer Configuration within gpresult, we can follow steps below.

Logon this machine using administrator account.

Open CMD (run as Administrator).

Type gpresult /h C:\gpo.html and click Enter.

Open gpo.html and check gpo setting under "Computer Details".

For checking User Configurations within gpresult, we can follow steps below.

Logon the machine using normal domain user account (that applies this gpo).

Create a folder named F1 in C drive.

Open CMD (do not run as Administrator).

Type gpresult /h C:\F1\gpo.html and click Enter.

Open gpo.html and check if there are these gpo settings under "User Details".

You can try to analyze the exact cause of the problem by capturing network packets. This is an article about packet capture:
