Hi hacmac, can you give us a couple more infos please? This error usually appears if you cancel the login process by yourself, you’re saying this is not the case here? Can you give me the exaxt steps you took before this appeared?

Are you on WiFi or LAN? Do you have any adblockers / scriptblockers or VPNs active that you could temporarily disable to test if that helps?
