    I'm experiencing the same issue as described above. I have 2 visual studio projects. If I log into the backoffice of project 2 while also running project 1, project 1, breaks with the following errors. enter image description here

    First thought was that it probably had something to do with the authentication cookies, but deleting them, closing visual studio and the browser doesn't help. If I close everything and restart, after couple of tries it works again.

    Any idea to further debug this?

    Did you find a solution to this? Getting the same right now.

    EDIT: For me the issue resolved on it's own ... My hypothesis is that it had something to do with authentication cookies/session/whatever.

    Did anyone find a viable solution for this? This issue still exists in v 8.17.0. I can temporarily get around it by setting the server date ahead by a day but this affects all other apps on that server to have the wrong date. Thank goodness the front end of the application still works, but it's critical that the backend function at all times as well.

    Thanks.

    I am having this exact issue with all my U8 installs after a hardware change. Only U8. Can't login and I am seeing the exact same issue. I do recall the server tech telling me he needed to change the server clock at somepoint during the transfer. Any help appreciated.

    Update: After this hardware change (which involved the restoration of an image during a time that crossed into the next day) Umbraco 7 and 6 backend API response datetime stamps were reflecting the correct system date and time. Strangely the Umbraco 8 APIs were using GMT that was a full day ahead of the system date time clock. My guess is the fact that the system and reported times did not match prevented login. The offsets were somehow not getting calculated. App pool recycle and IISRESET did nothing. After a complete reboot of the server, the offsets were then calculated correctly on restart and normal login behavior occurred. So, my level 1 support advice is REBOOT.

    Cheers,

    Jamie
