Route added but website shows my ISP's IP. Not VPN IP

vaisam

I'm trying to route Slack via the VPN Connection.

https://www.robtex.com/dns-lookup/slack.com shows Slack has the following IPs

13.32.167.93
13.33.208.245
13.35.21.158
13.35.142.159
13.249.44.166
52.84.246.60
54.192.58.244
54.203.112.76
54.230.29.35

I've added all of them to /etc/openvpn/server/server.conf

push "route 13.32.167.93 255.255.255.255"               # slack.com
push "route 13.33.208.245 255.255.255.255"              # slack.com
push "route 13.35.21.158 255.255.255.255"               # slack.com
push "route 13.35.142.159 255.255.255.255"              # slack.com
push "route 13.249.44.166 255.255.255.255"              # slack.com
push "route 52.84.246.60 255.255.255.255"               # slack.com
push "route 54.192.58.244 255.255.255.255"              # slack.com
push "route 54.203.112.76 255.255.255.255"              # slack.com
push "route 54.230.29.35 255.255.255.255"               # slack.com

and restarted the vpn server: systemctl restart openvpn-server@server

When I connect the client, the routes are correctly showing in the log files.

When I login to Slack, I get a default email from Slack saying "New sign-in detected from the xxxx IP" and the IP xxxx is of my ISP and not of my VPN server.

What could I be doing wrong? Please help.

Thanks
