Receiving "The antiforgery cookie token and request token do not match" on Login #5148

ABP Commercial 7.2.1 / Blazor Server / EF / Non tiered / Separate Host and Tenant DBs / Lepton Theme

Hi, we are receiving the following exception in certain circumstances when a user logs in (see below for full log details)

The antiforgery cookie token and request token do not match.

So far, we only seem to have been able to replicate this in a Safari browser running on a Mac. We have not been able to replicate the issue on Chrome or Edge whether on a PC or Mac.

Steps to reproduce:

1. Start with a clean slate by clearing the browser cache
2. Login as a user
3. Logout
4. Login as the same user
5. Logout
6. On the third login as the same user, the user receives a HTTP 400 AN INTERNAL ERROR OCCURRED DURING YOUR REQUEST! message.
7. From that point the user cannot login again without an exception (even if using a new tab or restarting the web browser). Additionally any invalid credentials entered causes the exception instead of the user friendly 'Invalid username or password' message.
8. The only way for the user to login again at this point is to clear the browser cache

The above steps are very repeatable, but it is a strange sequence of events. This is the only way we can reproduce, but a few clients have reported the issue as occurring randomly.

We are using HTTPS only have not found anything in our research that seems to apply to our situation.

Any suggestions on what might be going on here and if there are any known issues and/or workarounds?
