No Kernel Connected and Terminal Not Found - Azure ML Studio Notebook

My notebook suddenly unable to detect or connect to kernel. Prior to the incident, I crashed my kernel twice but able to restart perfectly fine. Then, cannot connect a few minutes later. My compute instance is running and I tried restarting/create new compute but did not solve it. Another detail is my colleague has no issue whatsoever as we both use the same workspace and network. I tried using compute instance created by my colleague but it also did not work. I see some users had this issues before but i don't see any helpful solutions to this matter.
Update: I tried running a designer job and it stuck in queue indefinitely. It works fine before. I might have issue with connecting to the compute instance for some reason. User's image

Hi @Amir Firdaus Bin Abdul Hadi,

Thank you for reaching out to Microsoft Q&A forum!

When encountering issues with Azure Notebooks failing to detect or connect to the kernel, especially after a kernel crash, several steps can help troubleshoot and potentially resolve the issue:

Might this issue would be intermittent, it could be due to a temporary network or server issue. In this case, you can try again later to see if the issue has been resolved.

Try to Clear browser cache and cookies and also try using a different browser.

Try restarting or recreating your compute instance.

Check the logs for any errors or warnings.

Also, try to check the troubleshooting documentation to resolve the issue.

I hope this helps! Thank you.

Hi @santoshkc Thanks for the reply. But I had try your suggested steps but yet to resolve.

This issue happened last friday, not sure if it still temporary network issue

I have tried both edge and google with cleared cache

Restarting and creating new compute instance also did not work. Using shared compute instance created by others also did not work.

the log that i found is attached to the question and below is from inspect web console
