Jenkins Load Error - jenkins

Question

I am new to jenkins and I recently installed jenkins on my local system. When the installation was complete and the Jenkins Dashboard had to load, I got the error as in the snapshot attached.
The system is connected to VPN as its office system.
Kindly let me know what changes I should make to get jenkins up and running.
I checked the log file of jenkins and found that jenkins service abruptly ending because of jetty issue as below:
