      Mod Note

      Some things you could try to troubleshoot if your servers aren't loading or if you get a "Internal Exception: java.net.SocketException: Connection Reset" Error since 1.17:

      1. Make sure the new OpenJDK16 is allowed through the Windows Firewall.
        1. Press the Windows Key and type "firewall."
        2. Click on "Allow an app through Windows Firewall."
        3. In the new window, press "O" on your keyboard and look for "OpenJDK Platform Binary."
        4. If you find it, make sure both the checkbox on the left, as well as both checkboxes on the right, are checked. Then click OK and try Minecraft again.
        5. If you do not find that entry, click Change Settings, then click Allow another app...
        6. If you're using the legacy launcher, click Browse, then navigate to: 
          C:\Program Files (x86)\Minecraft Launcher\runtime\java-runtime-gamma\windows-x64\java-runtime-gamma\bin\javaw.exe

          and click Open, then Add.

        7. If you're using the Microsoft Store launcher, click Browse, then navigate to: 
          C:\Users\user\AppData\Local\Packages\Microsoft.4297127D64EC6_8wekyb3d8bbwe\LocalCache\Local\runtime\java-runtime-gamma\windows-x64\java-runtime-gamma\bin\javaw.exe

          and click Open, then Add. (Note: Your Microsoft. folder may differ from the path here. If so, navigate through each Microsoft. folder in the directory until you find the right one)

        8. Click OK and try Minecraft again.
      2. Try disabling all VPNs, Hamachi, Antiviruses, and firewalls (especially third-party firewalls)
      3. Try on another connection, such as mobile data via wireless hotspot or USB tethering.
      4. Try creating a new profile in the launcher (Installations -> New), setting it to 1.18.2 (not latest release), and trying that new profile.
      5. Try the following on Windows:
        1. Press the Windows Key, then type cmd.
        2. Under 'Command Prompt,' click Run as administrator
        3. Type netsh winsock reset and press Enter.
        4. Type netsh int ip reset and press Enter.
        5. Type ipconfig /release and press Enter.
        6. Type ipconfig /renew and press Enter.
        7. Type ipconfig /flushdns and press Enter.

      FIXED THE ISSUE.
      Firewall was blocking online access for 1.17 and I told it to stop.

      I usually play on 1.8 or 1.16 and they work fine, but in 1.17 I'm unable to join any servers. I'm a member on an SMP server which just updated to 1.17, but I'm unable to join, which sucks.
      All the servers on the list are Pinging, and trying to load realms gives me this error message:

      An error occurred (500):
      Could not connect to Realms: Connect timed out

      TL;DR

      every other version:

      full list of working servers (joinable and all)

      1.17:

      full list of "Pinging..." servers (not so joinable - they just keep loading)

      Worth mentioning that this was also happening with the pre-releases.
