503 from /config-v2 after successful login

NeuVector
1

Hello!

I’m a little puzzled by an intermittent issue when logging in to the NeuVector webUI:

  • login seems to succeed, and the user is taken to the dashboard
  • a split-second later, the user is sent back to the login-page, sometimes with a Session expired error (red text under the login buttons), sometimes with No healthy upstreams

Checking the network trace, I can see a [503 Service Unavailable] error from /config-v2 after the successful login (and loading of other data).
This has been observed both with a user defined in NeuVector, as well as with SAML logins; In the latter case, the user in question even appears in the user list as a SAML user, with the correct role.

Anyone seen this (or similar) before?
