Your logs show that OpenConnect repeatedly tries to detect a live
peer, and gives up after ~10 tries. Puzzlingly, it never attempts to
*reply* to the DTLS DPD request.

Are you saying that during the intervening ~300s, you can't access
*anything* on the network? Can't even ping the DNS servers, or get
packets back from them (e.g. `dig @10.90.110.51 @10.90.110.52
some.server.noaa.gov`)

Questions:
- What additional details do you get if you run with `-vvv --dump`?
(much more verbose logging)
- Does --no-dtls make any difference?
- Have you tried building OpenConnect v8.05 from source? MTU detection
is significantly improved, and this may make a difference.

Thanks,
Dan
