I have been using Open VPN for almost a year now with two laptops. One laptop is working well with the Open VPN . Then about a week ago out of the blue my other laptop stopped working. It shows that it is connected to the VPN server, which is a Synology NAS with no errors, but then my wi-fi adapter immediately shows a yellow triangle on it and I lose my internet connection and I am unable to access my NAS.
I already tried reinstalling the TAP adapter driver, restarting the TAP adapter, checked that the DHCP Service is running, Flushed the DSN, Reset Winsock, Disabled Anti-Virus, and turned off Firewall. I also tried a restore point to a time that is was working, none of these procedures has fixed the issue.
I have pasted the Open VPN Log below:

Thank you in advance for any suggestions on how to fix this issue.
