Background:
All networks are normal, we run test connection on the UI interface, see the test failure and we check the log find the information below. after a period of time, the test was normal again and we didn't make any configuration changes. So we would like to ask what the following error reporting information means, why it appears, and what methods can be used to deal with it, many thanks
