[Archivesspace_Users_Group] Can't connect to frontend server: how to reset flash errors ?

[Steven Majewski]

Tried to merge two resources. It failed. Tried to go back to resource browse page.
Got “We’re sorry, but something went wrong.” message. 
Tried to load home page and got same message. 
Tried to shutdown and restart server. 
Get the same “We’re sorry, but something went wrong.” message. 
Repeat with same results.  

I can connect to the backend server and the public server, but not to the frontend server at any URL I’ve tried. 

Any idea what I need to reset ? 

It looks like it’s trying to flash an error message about the failed merge, but getting an error on that attempt.
