Hi Everyone.
Hope everyone has had a great weekend.
I have been using hack the box straight from my laptop, never had a problem connecting. Following advise from HTB I decided to build a virtual machine running parrot OS, finished the updates last night, the OS runs spot on.
I downloaded my connection pack as normal, tried to connect to the HTB vpn but I noticed the following error.
2020-10-18 18:26:53 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
2020-10-18 18:26:53 TLS Error: TLS handshake failed
2020-10-18 18:26:53 SIGUSR1[soft,tls-error] received, process restarting
2020-10-18 18:26:53 Restart pause, 40 second(s)
2020-10-18 18:27:09 SIGINT[hard,init_instance] received, process exitingI am using “NAT” as the network setting which is default for virtual box, could that be the error. I will switch to “Bridged” setting to see if that makes a difference.
I will report back if it works.
Thanks
John
Quick Update…
I switched settings to briged network in Virtual Box, sadly no better, get the following error.

Thanks again

I changed the vpn file to TCP rather than UDP and now when I run the file it just sticks, so I will change that back to UDP and look at something else. See my current terminal output below

Interesting…
Following a guide I altered the vpn file again, this time I changed the port to 443 and the last two lines in the file were changed as well, now I get a TCP connection as you can see below BUT rather than keeping a connection to the vpn server, it automatically restarts as you can see below.
I will have another look at this tomorrow (gotta start getting ready for work 
gutted)
If anyone has any idea’s please give me a shout. After my terminal output I have posted what I have changed in the vpn file.
