PhpStorm - where are the FTP error logs located?

Question

I've got some weird and intermittent FTP issue with PhpStorm, where when transferring files the latter gets FTP error 3/5 times, while other FTP clients are fine. Unfortunately PhpStorm doesn't give meaningful errors, it just says:

Failed to collect files: Could not connect to FTP server on "----.com". 

I'd like to know exactly what the FTP said, the error flags, number, etc. I can't seem to find these info on PhpStorm.

Other infos:

1. Using latest PHP version as of date.
2. Compared with FileZilla, using same settings, including auth, transfer mode, etc. Identical!
3. Everything worked fine in PhpStorm until 3 days ago.

Answer 1

There are no separate FTP logs of any kind (not collected by default).

If you need to see such detailed FTP logs:

1. Enable such extra logging first: #com.jetbrains.plugins.webDeployment

   • https://www.jetbrains.com/help/phpstorm/troubleshooting-deployment.html#31fe36c1
   • or https://intellij-support.jetbrains.com/hc/en-us/articles/207241115-How-to-Collecting-PhpStorm-WebStorm-debug-Logs

2. Do your FTP activities

3. Check idea.log for details (this file contains all the logs from all subsystems).

   To access it use Help | Show Log in XXX Help | Show Log in XXX (where XXX will be default File Manager in your OS, eg Explorer on Windows, Finder on Mac)

4. Do not forget to disable extra logging once done (otherwise it will keep writing the extra info).
