Proton VPN mit VPN Manager einrichten

[Pepe1984]

Hallo zusammen

Ich habe auf meiner UNO 4K das VTI Image installiert und möchte gerne eine Verbindung zu einem Proton VPN Server herstellen.
Ich habe dafür den VPN Manager installiert und auf der HDD einen Ordner angelegt wo ich die ".ovpn" Dateien reingeladen habe.
Zusätzlich habe ich unter /ect den ordner "openvpn" angelegt.
Problem ist, wenn ich versuche eine Verbindung zu einem Server aufzubauen, schreibt er verschiedene Dateien in den openvpn ordner:

• pass.file (Da stehen meine Zugangsdaten drin - > Frage hierzu: Ich habe den Benutzer und das Passwort von Proton genommen was bei OpenVPN-/IKEv2-Benutzername steht
• openvpn.stat
• openvpn.log
• update-resolve-conf
• us-free-05.protonvpn.net.udp.conf

Bei den Dateien habe ich nix verändert.
Im Log steht folgendes:

Da fällt immer wieder folgendes auf:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed

Verbindung kommt keine zustande.
Was mache ich falsch? Bzw. wo liegt der Fehler?

Vielen Dank schon mal im Voraus für die Unterstützung!
