How to avoid "Timeout getting IP address" error

Rancher 1.x

Rancher V1.6.25
After getting error “Timeout getting IP address”, rancher will retry serval times, it will be success at last. But it waste me too much time.

Some log details:

There is not enough information here to give any insight. Does it happen randomly? Or after certain actions executed, if so, which one(s)? Logging from other infrastructure services regarding network and metadata usually helps to nail down what is causing the issue.
