How to find out the cause of Tool call timed out?

Discussion
1

In Agent mode, the chat function works, but all communications to the tool server for list_dir, read_file, and codebase_search result in the error “Tool call timed out.”

This occurs on the company’s LAN, but does not occur when tethering.

This seems to be a security issue, but when I searched the logs with Watch Guard, I could not find any logs that had been blocked.

Is there any way to find out the cause?

I’m also facing the same issue in a corporate environment the chat and edit works fine but when I try to use the agent mode, every tools gets a time out.
