Hello. Debian 4.9.168-1+deb9u4 (2019-07-19) x86_64 ISPConfig Version: 3.1.14p2 single Nginx This morning, I was unable to access the FTP through port 21. I could access it through port 22. I deleted Firewall, and the FTP has worked again. FTP software does not seem to be in question since the problem is the same with WinSCP and with FileZilla. I handed Firewall, unable to access again. TCP port: 20,21,22,25,53,80,110,143,443,465,587,993,995,2812,3306,8080,8081,10000 UDP Port: 53,3306
This solved the problem on the FTP, but it creates another one by preventing the opening of Roundcube.
Roundcube and pure-ftpd are not connected to each other. So a change if the passive port range has no influence on RoundCube.
You should know where log files are in your operating system. Try these commands as root: Code: less /var/log/roundcube/errors* ls -lht /var/log/nginx/*error*
I did a test at 8:56, 9:19 and 14:26. There do not seem to be any mistakes. It's as if Roundcube Webmail (redirected to Squirrel with the Perfect Server tutorial) was forbidden when Firewall is actived. Windows 10 I wanted to make a video to show the problem. The video software has unlocked the connection the time of taking the view. The connection was blocked again when I left the video software.
and which exact error message do you get in the browser? When you turn off the firewall, it starts working?
No error is indicated at various times when I activate Firewall. Mail error Mail warm The blocking disappears when I launch the video capture software and returns when I leave the video capture. The Firefox Developper browser (copy-screen) produces the error: Connection Error, could not reach the server, and in fact, there are two messages although it says there is none (it says "La boite courriel est vide"). The Edge browser works normally. Chrome browser provides error: RR_CONNECTION_TIMED_OUT
