Is this an MTU problem? Probably. It's best to change the mssfix parameter rather than directly changing the MTU of the TUN/TAP adapter. For example: mssfix 1200. You could also combine this with: fragment 1200. Note however that fragment will exact a performance penalty.

Eliminate any of those to make the test clean, and try adding "mssfix 1300" to your config to see if that fixes things. This tells OpenVPN's clients in your system to

When a packet is nearly the size of the MTU and when you tack on this encapsulation overhead, it is likely to exceed the MTU of the outbound link. That’s where IP fragmentation kicks in – which could lead to performance Tunnel UDP MSS-Fix: Disabled; Additional Config section: Paste the below data; reneg-sec 0 persist-tun persist-key ping 5 ping-exit 30 nobind remote-random remote-cert-tls server route-metric 1 4.
