Problems Logging in

Why does TradeMe keep rejecting my new password when I try to log in with it? This is the second time I have experienced this after using the password regularly for some time. So I create a new password and then the new one is rejected. I have created a new one twice this afternoon and the same thing happened each time. It is VERY annoying! I even tried the chat bot this afternoon but after a couple of basic questions it sent me a message to the effect that it was not working at present! Please tell me : what is going on? It logs me out consistantly and then doesnt register the password or username Both app and desktop/internet browser Even when uninstalling or clearing cache/data Been taking ages to connect amd then repeats issue
