Hi Kulta,
Based on your provided informations, I have some suggestions for you. Please try one by one then let me know the result :

• Check for a Proxy block many services as Discord, Epic,..

Press Windows + R, type inetcpl.cpl, press Enter.

Go to Connections > LAN settings.

Make sure "Use a proxy server for your LAN" is unchecked.

Check "Automatically detect settings".

=> Restart your browser/PC.

• Reset Network Settings such as DNS, Winsock, and IP stack.

Open Command Prompt as Administrator and run these commands one by one:

netsh int ip reset 
netsh winsock reset 
ipconfig /flushdns 

=> Then restart your PC.

• Check Windows Firewall or Antivirus may block traffic especially outbound connections like Discord.

Try disabling your antivirus/firewall temporarily.

Or go to Windows Defender Firewall > Allow an app or feature and make sure apps like Discord or Epic are allowed.

• Check Hosts File might be blocking certain websites.

Go to: C:\Windows\System32\drivers\etc\hosts

Open hosts in Notepad as Administrator.

Look for any entries blocking discord.com, epicgames.com, microsoft.com, etc.

Delete those lines and save the file.

Finally, You should check on Router or DNS Settings that may have parental controls, DNS filters, or firewalls blocking certain services.

• By trying to switchto a public DNS:
• Go to Network Settings > Adapter Options > Right click your adapter > Properties.
• Select IPv4 > Properties.
• Set DNS manually:
  • Preferred: 8.8.8.8
  • Alternate: 1.1.1.1
• Go ahead and check for a Proxy setting which can block many services (Discord, Epic, etc.).
• Press Windows + R, type inetcpl.cpl, press Enter.
• Go to Connections > LAN settings.
• Make sure "Use a proxy server for your LAN" is unchecked.
• Check "Automatically detect settings".

=> Then click OK and restart your browser/PC.
