OVPN Client Unkown Error 1450

Post by eemmee » Tue Aug 07, 2018 9:09 am

Hi All,

I hope this is the right section!
I just set-up an OpenVPN server ubuntu based (I used this script to install: https://github.com/Nyr/openvpn-install), then I copied on a Windows machine the .ovpn file and allowed the traffic on the firewall.

The connection seems to work flawlessly, but, on the windows machine, I got the log full of: " write to TUN/TAP : Unknown error (code=1450)" and "read from TUN/TAP : Unknown error (code=1450)". I tried to google those error unsuccessfully, do you have any idea?

Thanks!

I used this script to install: https://github.com/Nyr/openvpn-install
Try running the script with the default values.

Sorry?

I had the same error code also without using that script and installing it manually. I don't look for a solution,Ii'm looking for an explaination of what this error code means!

It is a Windows error code not an Openvpn one ..

Googling for it tells me that 1450 is Microsoft's way of saying:
  • "Windows is crap but we are not going to admit it"
The list of reasons is endless .. Could be SQL, could be memory management or even registry corruption ..

Basically, they don't know so how should we ?

It's enough, Thanks!

I thought it was an OVPN specific error, not a Windows one. Thank you!

I am looking into it .. but I have never seen this one before.

I presume that you are not actually using --port 0 (zero)

Is this a Windows machine a Virtual machine ?

I'm using the default one port 1194 UDP. The Windows Machine is a physical notebook with Windows 10 PRO 1803.
I'm using the latest OVPN (V. 2.4.6).

Thank you again!

Can you try again but remove this from your client config (for testing):

Code: Select all

setenv opt block-outside-dns
comment it out for now with a preceding '#'

I created a new Win 10 1803 PRO VM, installed OVPN (same version) and copied into the .ovpn file.
I got no error there (even with block-outside-dns uncommented), so I think that is a notebook problem.
Settings and tunnel are OK.

As long as it works, I think I'll accept that error. When I'll have time I'll try to dig into this problem more.

Thank you!

If your install worked on another machine then this does indicate a problem with the first machine.

We have some info here, it is a little out of date but still of use.

Anti-virus programs can sometimes interfere as well as other VPN software.
Uninstall everything like that which you don't need.

If you do find out what is causing the problem then please let us know.
