Managing files every 2 minutes or so he throws me Reconnection

I rewrite a php file and click Save and sometimes it works fine and sometimes it sends me to reconnect.

What should be done?

Make edits locally and upload after.
Use FileZilla or alternative FTP client.
We are aware of disconnection issue when services are busy, just don’t make file manager your go to thing for making edits as by the time you’ve made a few changes and hit save you’ll be bumped out and changes lost
