Workspace Installation Error

I am having trouble setting up ONLYOFFICE on my web server:

Intel(R) Xeon(R) CPU E5-1630 v3 @ 3.70GHz (8 core(s))
CentOS Linux 7.9.2009 (Core)
RAM 128 GB
HDD: 500 GB SS

I downloaded using: wget and ran "bash -md “”.

I am receiving the error “The following TCP Ports must be available: 80, 443, 25, 143, 4190”

These ports are available, and our Firewall is open for those ports too. Do you know what could be causing the problem ?

Hello @chicagola
Is it fresh OS? I mean no other apps are installed. Usually we recommend to use totally clean server for portal installation. It’s necessary to avoid dependencies and port conflicts.

You can run a simple test, try to reproduce the installation scenario on fresh OS without firewall in front of it. Will the result be the same? Also you can check if some ports are occupied with netstat -tuplen command.
