Invalid Application Certificate
Step 2: Open the scatter point details link and obtain the corresponding captured packets
Step 3: Packet capture analysis (Invalid certificate Error corresponds to analysis of TLS protocol-related packet information in the captured packet)
Filter rules:
1.
Judging from the packet capture, after the server notifies the client that the server_hello message is sent, the client returns an unknown certificate warning: Alert (Level: Fatal, Description: Certificate Unknown). Combining the data in the report, it is found that the "certificate invalid" Error is an accidental phenomenon, so it is ruled out that it is a certificate problem.
Step 4: Instant Testing result (reproduction)
Use 8339781Probe and specify to access: 122.224.250.220 target Host and the result is normal.
Step 5: Solution
The feedback was that the Network link fluctuation caused the data transmission to be Exception, which caused the browser to fail when verifying the certificate. The recurrence has returned to normal.
