You can see here it stucks for almost 2 hours, it should be continues trying if some network problem happened. Even at this moment the network recovered, it stopped trying.

Steps to reproduce

  1. Run server and client for a long time...
  2. Maybe some temporary network unstable problem happened for a short time
  3. And this happened (frpc stopped trying reconnect)
