After making changes to the FTP project, the site stops working for a while?

Question

FTP

Good afternoon!
The project is hosted on a server, hosting seems to be normal.
Phpstorm is configured to sync via ftp when saving changes to a file.
After saving the changes, the site stops working for a while.
There are no critical errors in the code.
I enter ulr manually and everything starts working.
What could be wrong?
Thank you.
