Connection issues can come from several different sources, so it's hard to pin one down right away. We do have a rundown of the most common sources of connection problems for you:
• Enable 'Game Mode' in your BIOS and/or graphics card
• Do not log into the client, then locate and delete the 'mft.myp' file. This will force the client to patch and fix any corrupted or missing files. If that won't resolve the issue, we recommend you first perform a clean install of the client(s), and remove any third party files beforehand, such as custom UIs. After the reinstall, restart your machine in safe mode with networking enabled and see if you can load into the client. If you can, it indicates there is a driver conflict or a conflict with another program running in the background. You may wish to disable/close any programs running in the background one by one to see which is causing the issue; this would include antivirus and firewalls.
• Ensure all drivers and custom UIs are up-to-date by checking manufacturer websites directly. Additionally, try to disable any customer UIs to check for different results.
• Ensure your firewall and antivirus program is not blocking any content and that you don't have any custom UO server/shard entries in your hosts file (C:\Windows\System32\drivers\etc\hosts)
• Start by force-closing the game and re-starting it
• Ensure there are no conflicting parental controls set
• If you have a weak or unstable network connection, this will keep the game from connecting. Try waiting until you have a better connection and then restart the game as described above.
• Disconnect and then re-connect to the network that you're trying to use. This can sometimes reset and clean up your connection.
• If you are set up to connect via proxies, disable this option and connect without them. The proxy connection could be causing the problem.
• Try connecting via a secure VPN connection and try again after disconnecting from VPN.
• You may change your Power Saving settings for higher performance, this will favor performance, but may use more energy.
• If you are connecting from school or work (or a similar location), there can be restrictions in place when connecting to certain sites and servers. In some cases, this can prevent the game from connecting when using that network. This can also be true if your computer was issued through school or work. In either case, follow up with your IT Department to confirm.- Likewise, if you are connecting at home, check the status of your home network to ensure that it's working as it should.
