As I following through this tutorial I installed OpenVPN on my server https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-18-04
and I needed to limit bandwidth for the users so regarding to this tutorial I set a bandwidth limitation for the server
https://netbeez.net/blog/how-to-use-the-linux-traffic-control/ I just used 2 commands for set limit for bandwidth
apt-get install iproute2
tc qdisc add dev eth0 root tbf rate 1mbit burst 32kbit latency 200ms
Also I set sever.conf up with the underneath configuration
sndbuf 0
rcvbuf 0
and add these lines to the ovpn client file
sndbuf 393216
rcvbuf 393216
push "sndbuf 393216"
push "rcvbuf 393216"
but unfortunately my openVPN is unstable and it doesn’t work well, it just work for a few seconds and after the seconds it Interrupts the internet traffic.
so is there anything else for limiting the bandwidth for each user in DigitalOcean Droplets?

Heya,
Just came across this answer and decided to write some general guidelines for anyone who comes across this in the future despite the old question.
It seems you have configured traffic control tc and buffer settings in the server and client config files. However, if you’re still facing issues, you can try the following:
- Check logs on your OpenVPN server to see if there are any errors or warnings that may provide insight into the issue. These logs can typically be found in
/var/log/openvpn/openvpn.logor/var/log/syslog. - Consider using a different method for bandwidth management, such as
Wondershaper(a wrapper for tc) ortrickle(a standalone userspace bandwidth shaper). - If possible, test without bandwidth limits to confirm if the limitation is causing the issue.
If you need further assistance, please refer to the OpenVPN troubleshooting guide and DigitalOcean OpenVPN tutorial.
Hope that this helps!
