Can't log in after upgrading to Tyk 2.8


We are trying to upgrade to Tyk 2.8 and Dashboard 1.8. We installed both of them from apt-get and now requests that previously succeeded are failing with 403 errors. We also upgraded Mongo to version 3.4.10 to correct for a vulnerability. When making requests, I don’t see anything in the Log Browser, and nothing shows up in any of the logs (gateway, dashboard, pump).

When you reply, I can send our configuration files over email.
