The problem is Updater.cpp

There is a question about the code block, it says that the read timeout is 30 seconds.

But in fact, much more time passes. A small update log in which the following occurs:

• the beginning of the update
• disabling ETH
• enabling ETH
  The update does not continue, but the timeout does not work after 30 seconds. It only worked after 5.5 minutes.

Why is this happening?
