Win 10 upgrade TLS key negotiation failed to occur within 60

[help_me_please]

I have just upgraded from Win 8.1 to win 10. I now cannot connect the server.
Many other clients continue to connect from my local network and from other networks. All are running win 7 or win 8.
I have not changed anything in my client .ovpn

I have uninstalled the TAP-Windows Adaptor V9 and then re-installed again with OpenVPN

Here is the log:

Difficult to know if you --mute half the logs ..

Tue Oct 20 07:49:33 2015 us=384049 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

I think you have overlooked a firewall setting.

I am sorry for wasting your time. I have just resolved the issue. For some reason the windows upgrade corrupted the .crt file. Thanks.

For some reason the windows upgrade corrupted the .crt file

That is new .. and quite unlikely ..

I have just resolved the issue

Could you explain your resolution please ?

You are not wasting my time as my time is worthless

Thank you for your interest.
I agree it surprised me that the WIN upgrade could affect the .crf file.
I originally had securepoint on my PC before upgrade. This failed to work after the upgrade.
I thereofre installed openvpn but copied the keys/cert files to the right place for openvpn. It seems that the .crt file
that I copoed was corrupt. I think it bacame corrupted by the WIN upgrade.
I copied a backup of the.crt file to the right place to overwrite the corrupt one and this resolved my issue.
Thank you.
