When I enable the Cloudflare proxy (i.e. orange network), I get the following error when trying to use OpenVPN
WARNING: Bad encapsulated packet length from peer (18516), which must be > 0 and <= 1626 – please ensure that --tun-mtu or --link-mtu is equal on both peers – this condition could also indicate a possible active attack on the TCP link – [Attempting restart…]
This works fine if I change the network to gray (i.e. bypass proxy). Any suggestions how to fix this?
