Troubleshooting OpenVPN client on RouterOS 6.27

Hi,

I try to troubleshoot an OpenVPN connection that does not initialize. I can ping the OpenVPN server, another IP router with PAT is in between. the only thing I see is

15:12:43 ovpn,info ovpn-customer-side: connecting...
15:13:46 ovpn,info ovpn-customer-side: terminating...
15:13:46 ovpn,info ovpn-customer-side: disconnected
15:13:56 ovpn,info ovpn-customer-side: initializing...
15:13:56 ovpn,info ovpn-customer-side: connecting...
15:14:59 ovpn,info ovpn-customer-side: terminating...
15:14:59 ovpn,info ovpn-customer-side: disconnected
15:15:09 ovpn,info ovpn-customer-side: initializing...
15:15:09 ovpn,info ovpn-customer-side: connecting...
15:16:12 ovpn,info ovpn-customer-side: terminating...

Can I do something to get more info out of the RouterOS as of why the connection does not come up?

Any hint is appreciated
Kind regards
