We announce hereby the decommissioning of TCP as transport protocol for OpenVPN connections by 1st of October 2024 and solely support UDP. The goal is to reduce the complexity of our service and simplify operations, while TCP as OpenVPN transport layer does not bring any effective benefits in terms of data connectivity performance. On the contrary, it may produce head of line blocking and get particularly inefficient when transporting a TCP based application (see also https://openvpn.net/faq/what-is-tcp-meltdown/). In order to achieve reliability at the application layer, it is enough if the application itself uses TCP transport (e.g. http, https, ftp, ssh).
Please contact our support in case your Internet service provider blocks UDP traffic, which would then prevent you from establishing OpenVPN connections with our platform over UDP and hence make TCP the only viable alternative (see also https://openvpn.net/faq/why-does-openvpn-use-udp-and-tcp/).
