Why is this happening with VPNs?

Question

openvpn

Good afternoon. For some time now, this picture has been happening periodically on some clients ...
You delete all connections - it reconnects normally

Occurs with win10.

OpenVPN up on Mikrotik CHR, more than 500 clients, if it matters... Gigabit license bought

Answer 1

In the settings of clients that cling to the VPN, set up a longer connection drop-down timer so that they do not cling more often than 2-5 seconds ...
Or see / edit the Max MTU and Keepalive Timeout settings in microt in the OVPN server properties
