I have a VPN connection on my home computer to my remote working computer, but when connection is open, I can't visit some websites on my home computer. However, online services for an IP address detection show the same IP address whether the connection is open or not.
Why does it happen and how to solve this trouble?

Could be many reasons ..

I read this, but haven't yet understood what to do with this information. My OpenVPN version is shown as 2.4.9-I601-Win10, and I don't know whether it is Access Server or Community Edition. However, I'm not a system administrator and may not understand a lot of terms

I can create this topic in other subforum if the current is not right for this, or provide some logs/configs needed

Read it again and again .. and try following some of the links and read them too.

Basically, you will find that OpenVPN is working fine but some websites don't work.

Probably, those websites are detecting you are using a VPN and are therefore blocking you.

I would consider not using websites that are so rude and intrusive ..

But if you manage to figure the following things out then add them to this thread:

Your server and client operating system
Your server and client version of OpenVPN
Your server and client configuration files in use
Your server and client log files
How to use copy/paste text

To save you some time, try using --block-outside-dns.
See the manual/howto for details.

I don't have information about the server because it is a server of my company and I don't have access to it.
About my computer:
- Operating system: Windows 10
- OpenVPN version: 2.4.9-I601-Win10

Configuration file .ovpn:

Client config

dev tun
proto tcp
keepalive 5 30
port 1194
client
resolv-retry infinite
auth SHA1
tun-mtu 12000
fragment 0
mssfix 0
auth-nocache
remote-cert-tls server
cipher AES-256-CBC
persist-key
persist-tun

There are also "remote" and "pkcs12" fields, but I'm afraid to show them because they include some confidential information.

Speak to the people that do.

If that is not an option for you then I am available for hire.
