Hi all,
For some reason, every VPN user keeps spamming the logs about a failed
UDP bind to port 443. I've attached an anonimized part of the log. The
messages keep coming even when I disable UFW.
Output of ocserv --version:
ocserv 0.10.11
Compiled with seccomp, tcp-wrappers, oath, gssapi, PAM, PKCS#11,
AnyConnect,
GnuTLS version: 3.4.10 (compiled with 3.4.9)
