Hey rajka, I am having issues with my tracker too (Canada citizenship tracker / Suivi de la citoyenneté canadienne (cic.gc.ca) ) I was able to register fine and logged in successfully previously but recently cannot log in and cannot even create a new account. The tracker recognizes my UCI and Application number and sends verification codes to my email but I keep getting "Unexpected problem. please try again later". I tried different browsers and cleared cache. I do not have VPN. Any thoughts what this may be?I suppose you received a HTTP error 403? Try disabling your VPN and try again.
