OpenVPN has a pretty strong interface and working mechanism and it works without many issues. While there are no major errors or bugs reported, you will not be having any problems while working with it.
Although some minor errors are inevitable and that you cannot do anything about. So, if you are getting an error while opening the configuration file on your OpenVPN, here is what you need to do.
OpenVPN Error Opening Configuration File
1) Restart your Router
If you are seeing it on the error log file and unable to make it work, you need to know first that the issue is usually caused by the router and there might be some error or bug with it. So, a simple restart on the router should be enough to do the trick for you. All you will need to do here is clear the error log first to ensure that you can check it again if the error recurs. After that, simply pull out the power chord on your router and then plug it back in after waiting for a few seconds. This is going to work perfectly for you and you will not have to worry about it again.
2) Reset the Router
Sometimes, the problem can also be caused due to some optimization in the configuration of your router settings and the error will persist if such a case is there. So, you will need to make sure that you are not having any errors in the error log. Then, you will need to reset your router to its default factory settings. This way, all the conflicting settings that might be causing your router to not access the OpenVPN configuration file will be cleared out and you will not have to deal with this mess ever again.
An important thing that you need to keep in mind is that a router reset attempt will also be triggering a firmware update request for your router. So, it might take a few minutes for your router to install and download the firmware update. This is a good thing since if there is some sort of issue with your firmware, it will be fixed as well. So, you just need to be patient and wait a bit until your router is up and running again.
3) Reinstall OpenVPN
There are also chances that your OpenVPN configuration file might have been corrupted due to some reasons or it might not be working optimally as it should. This will eventually cause you to face the problems and you can have them fixed by performing a reinstall for your open VPN. Simply uninstall the software application from your PC, restart it once, and then download the latest version of VPN client from their website and install it on the PC you are using. Enable it again on the same network and the error will be resolved for good.
