Bug in OpenVPN per site2site? Verbindung hält nicht

[AlxX0r]

Hallo,
ich habe 2 OPN's hintereinander & diese per OpenVPN site2site miteinander verbunden (die vordere als Server & die hintere als Client). In der vergangenheit hat das auch gut funktioniert, nur seit einem update vor ~1 Woche tut das nichtmehr. Der Client disconnected einfach immerwieder & ich weiß nicht warum.
Hier ein auszug aus der Log des Clienten:

aber auch wenn ich in der Client config die Haken bei "Don't pull routes" & "Don't add/remove routes" wegklicke, löst das nicht das Problem & er disconnected trotzdem immerwieder nur bleibt dann eben die Warnmeldung weg.

Ich habe es genau nach Anleitung eingerichtet & hat eig. auch immer so gut funktioniert, nun weiß ich nichtmehr weiter & hoffe es kann jmd. hier weiterhelfen?
Oder ist es doch ein Bug & ich muss warten bis die nächsten updates das Problem fixen?...
