Vouch this is a great list. Now I know who to cry to when I need something. 10/10 thank you

From my working on my DLL I have encoutered this problems many times now.

Roblox recently changed a lot of flags a couple days ago.

During this change they have made it that if Yara(Roblox's PE scanner AC) detects your DLL as an exploit, they will give you a temp ban.

It lasts around an hour I believe. The server will not let you join any game for about an hour. Then they will remove the block.

If you want to avoid this issue either bypass Yara or use an exploit which has it bypassed correctly.

Wish you the best of luck

Edit:

Don't bother trying to uninstall/reinstall Roblox.

Don't uninstall CE if you have it (As this isn't caused by it)

Don't google the error code as any information regarding this isn't accurate for this situation now.

Ignore any further replies on this thread. They won't be helpful
