Hi

I upgraded today most pangolin sites to NEWT 1.4.3
Some of the sites are running as docker containers and some as windows services.
What is the same for all of them is that I have a wireguard server on one of the sites which the clients connect to via a pangolin open UDP port.
Post upgrade that stopped working. Downgrade to 1.4.2 solved the problem.

Thanks

Same problem for me. Also using native WireGuard Server with raw UDP resource.
When I remeber right the initial handshake was working but was not able to hold the connection. Can check tomorrow.
Newt is running in docker with --native and network_connection: host

@oschwartz10612 please can you let me know if possible whether such a bug has been noted. If so I'll have to downgrade rather sooner than later all the sites as UDP is used quite a bit for lice camera feeds.

@Lokowitz I actually didn't add the --accept-clients in all cases, only some of them

Thank You!
