Hi, we occasionally receive the exception below right after signing in. When we click 'Reload' in the generic blazor error notification at the bottom of the page, the site loads correctly.

Thanks in advance, Brian

    Do you use a tiered application template? Is Redis up and running?

    Hi @gterdem, we do not used a tiered application template and we do not utilize Redis. We do, however, utilize the separated tenant schema option in our templated solution.

    Thanks
