CoderBoost

Connection fails

If connecting fails, work through this checklist.

  1. Account status: is your plan active? Have you used up your traffic? (See the dashboard home page.)
  2. Base network: can you get online normally with CoderBoost off?
  3. Other proxy software: is another app also setting the system proxy or running a TUN? Turn it off and try again.
  4. Device count: have 5 different devices already signed in this month? Remove unused ones in your dashboard.
  5. System permissions:
    • macOS: PAC mode needs permission to change network settings; TUN needs the system helper.
    • Windows: TUN needs administrator approval to install the system helper.
  6. Corporate network: a company firewall may block connections to edge nodes. Try setting an upstream proxy in the client, or ask your IT team.
  7. Clock: a badly wrong system clock makes login fail; turn on automatic time sync.
  8. Logs: in the client, Me → Logs, filter for ERROR; on Linux, cnb logs --level warn.
  9. Still failing: export the logs and contact support.
