Lots of TLS Errors from iPhone clients in server logs / fail2ban

Post by kmwoley » Sun Feb 10, 2019 9:21 pm

I don't have a connectivity problem - my iphone clients connect just fine - but it looks like they're also spamming the logs with multiple errors a minute:

...TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
...TLS Error: TLS handshake failed

It happens repeatedly when the phone screen is off; appears to stop when the screen is on.

I'd love to find a way to get rid of them, since they don't represent a threat and I'm trying to setup fail2ban which triggers ban rules on those errors by default.

Any suggested configuration changes to look at to resolve this, or is it expected behavior? Thanks!

Config: OpenVPN over UDP running under kylemanna/openvpn Docker
