Server connection halted, TLS handsake failed, no new selection of suitable server

[guidoevers]

Hi,

I hate opening this issue as a similar one had been open en closed before. I tried searching all of the internet but I can't get find an answer to this problem.

I have openpyn running quite well on a little linux machine, Vero 4K+. After a certain time, the connection would come to an halt. When I log in the log I see that openpyn tries to restart the connection to the same remote address. Also I see some TLS handshake errors.

I would have liked that when a connection to a certain vpn server is halted for whatever reason, the whole initiation process of finding a new most suitable vpn server would start. Reading the openpyn wiki I believe this is also how it is intended to work. I can't find out why this doesn't happen in my case. I hope anyone can push me in the right direction.

as mentioned in the other issues, a sudo systemctl restart openpyn kind of fixes the problem, but is not really a solution as it isn't automated.

I've made slight adjustments to sudo nano /etc/systemd/system/openpyn.service
