421 Proxy is closed--HELP

#1 Post by ENtotheB » 2023-04-28 13:30

Good morning:

I am a first-time poster and NOT an IT person by any means, so please take it easy on me LOL.

So, I downloaded FileZilla Pro earlier this week and had NO issues with it until yesterday. I kept getting the "421 Proxy is closed" error. I upgraded to the newest version of FileZilla yesterday, checked all my network connections, etc. and roped in IT--they couldn't find any issues and were already allowing the app. I've run every diagnostic and nothing is working. Like I mentioned before, I don't have an IT background & have tried just about everything. Any suggestions? THANK YOU IN ADVANCE! :) Below is the message log...

Unless there's some rogue firewall or other malicious network component injecting fake replies into the connection, something is wrong with the server.
