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 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 ?
