I want to premise that I am not an expert in connectivity, firewalls, routers, and related topics.
For the past two days, I have encountered an error when attempting to connect to my office VPN through the OpenVPN software. The error message I receive is as follows:
Tue Jul 18 12:34:52 2023 WARNING: Compression for receiving enabled. Compression has been used in the past to break encryption. Sent packets are not compressed unless "allow-compression yes" is also set.

It's important to note that this connection issue seems to affect everyone, regardless of their device or user account.
I am aware that we have a router in place, which is responsible for forwarding external requests to the pfSense firewall (I suppose?). Additionally, I have observed that attempting to access the router's portal using the public IP address (https://188.X.X.X) results in a timeout. However, I can successfully access the portal using the LAN IP address (10.X.X.X). I attempted to troubleshoot the issue by performing a telnet on ports 4443 and 1194, but both attempts timed out.
Fortunately, I have access to the pfSense portal, which allows me to make changes and gather information. With that in mind, would anyone be able to provide guidance and assistance in resolving this matter?
