Explanation
https://knowledgebase.paloaltonetworks.com/kCSArticleDetail?id=kA10g000000PMiD The PanGPA log on the GlobalProtect app records the events related to the user interface of the app, such as user actions, messages, and notifications . The PanGPS log records the events related to the service or daemon process of the app, such as connection attempts, authentication, and tunnel establishment2. The PanGPA process communicates with the PanGPS process on port 4767 . Therefore, the message "Failed to connect to server at port:4767" indicates that the PanGPA process failed to connect to the PanGPS process on port
4767. This could be caused by various factors, such as firewall blocking, antivirus interference, corrupted files, or incorrect permissions4. References:
